Abstract: International audience; The design of a simple and adaptive flight controller is a real challenge in aerial robotics. A simple flight controller often generates a poor flight tracking performance. Furthermore, adaptive algorithms might be costly in time and resources or deep learning based methods may cause instability problems, for instance in presence of disturbances. In this paper, we propose an event-based neural learning control strategy that combines the use of a standard cascaded flight controller enhanced by a deep neural network that learns the disturbances in order to improve the tracking performance. The strategy relies on two events: one allowing the improvement of tracking errors and the second to ensure closed-loop system stability. After a validation of the proposed strategy in a ROS/Gazebo simulation environment, its effectiveness is confirmed in real experiments in the presence of wind disturbance.

3. Predictive smart charging of plug-in electric vehicles for parking fleet scenario with modular converters

Author: Razi, Reza, Mehrasa, Majid, Hajar, Khaled, Gholami, Mehrdad, Hably, Ahmad, Bacha, Seddik, Labbone, Antoine, and RAZI, Reza
Subjects: [SPI.NRJ] Engineering Sciences [physics]/Electric power
Abstract: In recent years, smart charging of electric vehicles has been considered in various scenarios for all parties involved. However, the issue of smart charging is less explored in the parking lot scenario than in other ones, where the number of vehicles is typically greater than the number of charging points. In addition, the charging period is temporary, and modular converters are used to reduce costs in this scenario. In this paper, a modified algorithm is presented to connect each vehicle to the suitable and pursue the desired goals. The effectiveness of the proposed method is evaluated through simulation.

Abstract: International audience; In this paper, an application of evolutionary game dynamics is proposed in order to profit from the desirable features of mixed strategist dynamics in the solution of distributed resource allocation problems. The key idea of this approach is to define mixed strategies that represent the vertices of the convex hull of the set of feasible solutions defined by the constraints of the local optimization problems. With this approach, the dynamics of the state vector is restricted to a subset of the simplex. Details of the defintion of appropriate mixed strategies, payoff functions, and the multi-population modeling followed for this problem are provided.

Abstract: International audience; This paper provides a linear approach to compute the voltages at any node on a residential grid based on the house instantaneous load and the presence of charging Plug- In Hybrid Electric Vehicles (PHEV) on the grid (and the corresponding instantaneous consumption or injection). Based on this linear operation, the paper provides a detailed linear programming formulation of the problem of charging the PHEVs while providing a voltage support service to the grid. Multiple evaluation cases are included in order to test the ability of the approach to maintain voltages within safety limits and provide optimal consumption/injection policies. An additional case is included to prove the potential of the PHEVs to solve existing voltage technical issues on a residential grid.

Abstract: The control and design of mini aerial robots have received much attention within the automatic control community throughout the last decade. The main objective of this thesis is the control of two classical under-actuated systems : Planar Vertical Take-Off and Landing aircraft (PVTOL) and the quadrotor, a helicopter with four fixed rotors. The control laws developed take into consideration the bounds on the inputs with a very low computational cost which is crucial in real-time applications with limited embedded capabilities. Both the attitude and position control are considered in this thesis. The control laws are based on the global stabilization of multiple integrators with bounded control and fast predictive control., Les drones et les micro-drones font actuellement l'objet de développements très rapides. L'objectif principal de ce sujet de recherche est le développement de lois de commande permettant de contrôler deux systèmes sous actionnés classiques : l'avion à décollage et à atterrissage verticaux et le "quadrirotor" ou hélicoptère à quatre rotors fixes. La spécificité des approches développées est que les limites des actionneurs sont prises en compte tout en assurant un coût de calcul compatible avec une implantation et une exécution en temps réel sur un système informatique embarqué. La commande de l'assiette et de la position sont abordées dans ce travail. Les commandes proposées sont basées sur la stabilisation globale des chaînes d'intégrateurs linéaires et sur les techniques de commande prédictive rapide.

Abstract: The control and design of mini aerial robots have received much attention within the automatic control community throughout the last decade. The main objective of this thesis is the control of two classical under-actuated systems : Planar Vertical Take-Off and Landing aircraft (PVTOL) and the quadrotor, a helicopter with four fixed rotors. The control laws developed take into consideration the bounds on the inputs with a very low computational cost which is crucial in real-time applications with limited embedded capabilities. Both the attitude and position control are considered in this thesis. The control laws are based on the global stabilization of multiple integrators with bounded control and fast predictive control.; Les drones et les micro-drones font actuellement l'objet de développements très rapides. L'objectif principal de ce sujet de recherche est le développement de lois de commande permettant de contrôler deux systèmes sous actionnés classiques : l'avion à décollage et à atterrissage verticaux et le "quadrirotor" ou hélicoptère à quatre rotors fixes. La spécificité des approches développées est que les limites des actionneurs sont prises en compte tout en assurant un coût de calcul compatible avec une implantation et une exécution en temps réel sur un système informatique embarqué. La commande de l'assiette et de la position sont abordées dans ce travail. Les commandes proposées sont basées sur la stabilisation globale des chaînes d'intégrateurs linéaires et sur les techniques de commande prédictive rapide.

Abstract: International audience; Non-cooperative game problems such as pursuitevasion require a solution approach that takes into consideration the strategy of the opponents. To predict the strategy of an opponent in a game, its full information is required and more computation time would be spent. However, this requirement of the opponent's full information is not realistic. Also, the computation time required by the game-theoretic algorithm (GTA) could make the controller unimplementable for some systems. Conversely, Model Predictive Control (MPC) could be use to solve the same problem using only the states information on the opponent by solving minimization or maximization cost functions. In this paper, we compared the GTA and MPC algorithm using two autonomous nonholonomic ground robots. Several simulations were conducted in the absence and presence of obstacles, using different initial conditions. The results obtained showed that the MPC algorithm can achieve similar performance.

Abstract: International audience; The main challenge in hybrid wind-battery systems is the battery cost including investment and replacement. Thus, numerous studies have been conducted on cost minimization. Previous studies often focused on the battery sizing, while the battery performance has also the significant effect on the battery replacement and in turn battery cost. In this paper, a new approach is proposed to improve the battery performance and lifetime. We proposed an extended two-set battery model with new scenarios and formulation to achieve a balance between batteries and managing their power during prediction error. In this model, shallow charge/discharge cycles are eliminated, and batteries experience complete cycles. Furthermore, the battery availability is increased. The simulation results for a case study are presented and the results show the effectiveness of the proposed approach in comparison of conventional models.

Abstract: International audience; The world is shifting towards Renewable Energy Sources (RES) to meet the increasing demand. With proportionally high penetration of RES, the inertia of the grid tends to fall due to the incapability of these sources to participate in control mechanism. Also, due to the indeterminacy in the generation pattern, they tend to feed small signal disturbances in the grid due to the imbalance of generation and demand, which affects the frequency stability. In this paper, the affect of inertia emulation (IE) in the grid is presented to mitigate the small signal disturbances caused due to the change in load or due to the penetration of the RES. This work has considered Electric Vehicles for the application of vehicle to grid (V2G) towards frequency control. A cooperative control method, with V2G and synchronous power controller (SPC) based HVDC links, has been proposed towards the control of the fluctuations and a considerable decrease in the deviations have been observed. Several case studies are conducted and the results are presented to proof the concept.

Abstract: International audience; This manuscript explores the selection of appropriate mixed strategies (MSs) in a Mixed Strategist Dynamics (MSD) application for load management of Plug-in Electric Vehicle (PEV) fleets. This selection is based on the convenience of PEV owners, aiming to choose those MSs that privilege early high (or fast) charging rates when it is possible. The previously published MSD and Maximum Entropy principle (MSD-MEP) approach is revised and illustrated with several examples, specially in the context of selection of MSs. This revision allows a wider understanding of the method, and aims to inspire new contributions on domains where distributed optimization methods are pertinent. Results obtained without any management structure are compared to those obtained with the MSD-MEP approach under different scenarios, where full sets of MSs and reduced sets of convenient MSs are applied. The performance of the method, using conveniently reduced sets of MSs, is tested with real historical active power measurements, provided by the SOREA utility grid company in the region of Savoie, France.

Abstract: International audience; In this paper, a centralized model predictive control (MPC) is applied on a group of interconnected microgrids (MGs) with the main grid. The objective is to maximize the benefits for all the elements constituting the MGs in addition to the benefits of the main grid. The application of MPC in our study needs a forecasting information about energy prices, production power, and loads. The algorithm is tested on five interconnected MGs connected to the main grid. Results have shown the performance of the proposed algorithm, especially for the benefits of MG owners, the coordination between MGs while respecting of the constraints related to each one of them.

Abstract: International audience; The growing need of energy, global warming and recent nuclear power plant accidents have shown that renewable energies need to be developed for tomorrow's world. Wind energy is generally harvested using wind turbines. Unfortunately, these systems have some drawbacks such as their cost, and the amount of steel and concrete used for construction. As their size grows, their complexity increases exponentially. This paper studies an alternative solution for the production of wind energy, using a kite's traction force. The aim of this paper is to control the amount of energy produced by the kite, and to be able to fly it safely in the presence of strong wind gusts. Our theoretical work has been implemented in a scale model flying autonomously in a wind tunnel. The proposed control strategy has led to control the system output power with an accuracy greater than 95%, with unknown wind speeds varying from 7.5 to 9 m/s.

Abstract: International audience; This paper proposes a modified Perturb and Observe (P&O) Extremum Seeking Control (ESC) technique in presence of multiple maxima. ESC is applied to single-phased grid-connected photovoltaic (PV) arrays which have to provide maximum power irrespective of solar irradiance conditions. In particular, partially shadow conditions may lead to steady-state power curves exhibiting multiple maxima. The power harvested from the PV generator is injected in the single-phased power grid by using two power converter stages: step-up DC-DC converter and DC-AC inverter. When multiple power maxima exist, the amplitude of the perturbation signal plays an important role in successfully tracking the global maximum. Two amplitude modulation strategies are analyzed for the same case study: amplitude modulation by using a first-order-system-response signal and amplitude modulation by using small duty ratio square-wave signal, respectively. MATLAB®/Simulink® numerical simulations are presented in order to assess the two approaches comparatively.

Abstract: International audience; Most kite wind power systems have a great drawback that wind turbines do not have: they cannot stay in the air if the wind is not strong enough, [7-16]. As a consequence, most of the kite systems need to land when there is no wind, and to take-off once the wind is strong enough. These maneuvers are quite risky because generally the wind gets weak and turbulent close to the ground's surface. Moreover, as the wind can be strong enough at high altitude and weak close to the ground, it might lead to losses in energy production. From a material point of view, "classic" landings and takeoffs need a landing zone, ground handling or infrastructure (such as pylons) that reduces the advantages of kite systems. Some ideas, such as embedded motors or helium balloons, might solve this problem, but they have their own drawbacks such as the weight of the motor and its battery, the necessity of a conductive cable or the need to refill the balloons. The following paper studies a solution called "reverse pumping". It basically consists of providing kinetic energy to the kite by pulling the kite with a rope. This kinetic energy is then transformed into potential energy by gaining altitude. This technique allows to keep the kite airborne in total absence of wind. This paper will study the reverse pumping principle, the constrains on the aerodynamical model, flight simulations and will present the experimental setup used to validate the theoretical study.

Abstract: International audience; - In near future, Plug-in Hybrid Electric Vehicles (PHEVs) will replace conventional vehicles. Considering the bidirectional nature of PHEVs, this paper proposes a Housing Peak Shaving Algorithm (HPSA) for housing composed of a PHEV. In addition to prohibiting the electricity subscription overruns caused by PHEV charging, HPSA reduces subscribed power. The application of this algorithm at a group of housing forming a low voltage residential electric grid will help to minimize the aging rate of MV/LV transformer and to respect the standard related the voltage quality of the energy supplied. Thus, HPSA can be assimilated to both Vehicle-to-Home (V2H) and Vehicle-to-Grid (V2G) concepts.

Abstract: International audience; Plug-in Hybrid Electric Vehicles (PHEVs) will strongly penetrate in the car fleet. Based on databases of the houses Daily Loads Profiles (DLPs) and on a probabilistic algorithm of PHEVs connections in residential electric grid areas, this paper determines the minimal charging current or PHEVs charging power which assures that the batteries reached the desired State of Charge (SOC) at the departure time without any charging restriction during peak hours. A dynamic optimization algorithm programming which defines an optimal constant charging current for the PHEV is developed. If charging occurs at home, the application of the proposed optimal algorithm on 10 000 cases shows statistically that a load power chargers for PHEVs charged in residential electric grid areas equals to 373W (230Vx1.62A) ensures that 99.4% of the PHEVs batteries have a SOC equals to 100% for the next use.

Abstract: International audience; The search for novel renewable energy resources led to investigate a resource, that was once considered a complex, unpredicted and difficult to be controlled, that is sea waves. It has attracted a particular attention in western Europe, as waves on the Atlantic coast seem to hold a huge energy that needs to be exploited. In the course of this paper, an introduction into wave energy, as well as, some examples on energy conversion systems are presented. As a study case, a pumping-type system with a vertical displacement is considered. A formulation of the forces acting on its floating part is done in order to calculate its average power. Three basic methods of controlling the proposed system are explained and compared taking into account the case of regular and irregular waves.

Abstract: International audience; This paper presents a control scheme of a closedorbit kite generator system (KGS), which is a wind-based energy producing system with a relaxation cycle. Such a system is divided into two main parts: a kite with its orientation mechanism and a power transformation system. Starting from a given closed orbit, the optimal tether's length rate variation (kite's tether radial velocity) and the optimal orbit's period are found. A trajectory-tracking control is developed for the kite's orientation. The power transformation system controls the kite's tether radial velocity and transforms the mechanical energy generated by the kite into electrical energy that can be added to the grid. A Matlab/simulink model of the KGS is employed to observe its behavior, and to insure the control of its mechanical and electrical variables. In order to improve the KGS's efficiency in case of changing wind speed, a maximum power point tracking (MPPT) algorithm is proposed.

Abstract: International audience; This paper presents a control scheme of a closed- orbit kite generator system (KGS). Such a system is divided into two main parts: A kite with its orientation mechanism and a power transformation system. Starting from a given closed orbit, the optimal tether's length rate variation (tether radial velocity) and the optimal orbit's period are found. For the kite's orientation, a kite model is chosen and a trajectory-tracking control is developed. The power transformation system controls the tether radial velocity and transforms the mechanical energy generated by the kite into electrical energy that can be added to the grid. The proposed control strategy is tested on a Matlab/Simulink model of the KGS.

Abstract: International audience; High altitude wind energy (HAWE) is a new field of renewable energy that has received an increasing attention during the last decade. Many solutions were proposed to harvest this energy including the usage of kites and wings. In this paper, a novel wind power system based on a tethered wing is presented. An observer-based control strategy that avoids the need for precise knowledge of the dynamic model is then applied. Numerical simulations show the performance of the proposed control scheme which is validated in real time on an indoor experimental set-up of Gipsa-lab control system department.
