International audience; The greenhouse climate control is important in modern agriculture. It is also rather difficult to design: as a matter of fact writing down a "good" mathematical model, which takes into account strong meteorological disturbances, might be an impossible task. The control is here synthesized via a new "model-free" setting, which yields an "intelligent" proportional feedback controller, the tuning of which is straightforward, and even simpler than the intelligent proportional-integral controller, which was already utilized in a previous publication. Our control strategy is successfully tested via an experimental greenhouse. The comparison with the classic Boolean approach, which is popular among manufacturers, demonstrates the superiority of our viewpoint, which permits moreover an efficient actuator fault accommodation. It might be the first model-free fault-tolerant control, which works satisfactorily in practice.

Recent investigations on the longitudinal and lateral control of wheeled autonomous vehicles are reported. Flatness-based techniques are first introduced via a simplified model. It depends on some physical parameters, like cornering stiffness coefficients of the tires, friction coefficient of the road, ..., which are notoriously difficult to identify. Then a model-free control strategy, which exploits the flat outputs, is proposed. Those outputs also depend on physical parameters which are poorly known, i.e., the vehicle mass and inertia and the position of the center of gravity. A totally model-free control law is therefore adopted. It employs natural output variables, namely the longitudinal velocity and the lateral deviation of the vehicle. This last method, which is easily understandable and implementable, ensures a robust trajectory tracking problem in both longitudinal and lateral dynamics. Several convincing computer simulations are displayed., 9th IFAC Symposium on Intelligent Autonomous Vehicles (Leipzig, Germany, 29.06.2016 - 01.07.2016)

International audience; In spite of a large technical literature, an efficient climate control of a greenhouse remains a very difficult task. Indeed, this process is a complex nonlinear system with strong meteorological disturbances. The newly introduced ''model-free control'' setting is employed here. It is easy to implement, and has already shown excellent performances in many other concrete domains. Successful experimental tests are presented and discussed. They are compared to a Boolean approach, which is often utilized in practice.

Engineering and manufacturing industries ,Science and technology - Abstract
Byline: Michel Fliess, Cedric Join, Hebertt Sira-Ramirez Non-linear state estimation and some related topics like parametric estimation, fault diagnosis and perturbation attenuation are tackled here via a new methodology in numerical differentiation. The corresponding basic system theoretic definitions and properties are presented within the framework of differential algebra, which permits to handle system variables and their derivatives of any order. Several academic examples and their computer simulations, with online estimations, illustrate our viewpoint.

International audience; The control design of an artificial pancreas, a hot research topic in diabetology, is tackled via the newly introduced model-free control and its corresponding "intelligent" proportional controller, which were already quite successful in many concrete and diverse situations. It results in an insulin injection for type 1 diabetes which displays via constant references a good nocturnal/fasting response, but unfortunately a poor postprandial behavior due to long hyperglycemia. When a variable reference is introduced, that switches between a constant one, when glycemia is more or less normal or moderate, and an exponential decay reference path, when a high glycemia rate indicates a meal intake, the results in silico, which employ real clinical data, become excellent. We obtain a bolus-shaped insulin injection rate during postprandial phases. The hyperglycemic peaks are therefore lowered a lot.

International audience; This paper deals with a coupled longitudinal/lateral vehicle nonlinear control and road bank angle estimation. The control law is designed using the differential flatness property of nonlinear longitudinal and lateral vehicle model. An algebraic estimation approach is employed to estimate simultaneously the vehicle dynamic parameters (like lateral forces and roll angle) and unknown inputs (like road bank angle and corrective yaw moment). The control and estimation approaches use also the algebraic estimators to perform the filtering and the numerical derivatives of noisy measurements. To perform some coupled vehicle tasks like an automatic line keeping of straight or curved lines, a line change maneuver, obstacle avoidance, a combined control of longitudinal and lateral vehicle motions is required. Note that this controller is designed via steering angle and traction/braking torque of vehicle. Furthermore, some other parameters like road bank angle has an important influence on vehicle lateral dynamics behavior and control vehicle systems. For this, the algebraic based unknown input estimator is considered here to estimate road bank angle and consider a more realistic trajectories. Interesting results are obtained using real data which are acquired under high lateral accelerations.

The amplitude, frequency and phase of a biased and noisy sinusoidal signal are estimated via algebraic techniques. The methods which are popular today seem unable to obtain a robust estimation of those parameters within a fraction of the signal's period. The e ciency of our approach is illustrated by several computer simulations., L'amplitude, la fréquence et la phase d'un signal sinusoïdal, biaisé et bruité, sont estimées par des techniques algébriques. Les méthodes d'aujourd'hui ne semblent pas capables de fournir ces paramètres de façon robuste en une fraction de période du signal. Plusieurs simulations numériques confirment l'intérêt de notre approche.

International audience; The experience gained with numerous successful applications permits to revisit some points of model-free control. The numerical differentiation of noisy signals may be replaced by a real time parameter identification which is much simpler. The strange ubiquity of classic PIDs is explained as well as the almost universal utilization of ultra-local models of order 1. We show that even with a partially known model the utilization of an intelligent PI controller remains profitable. Two examples, an inverted pendulum and a heat exchanger, seem to confirm the superiority of model-free control with respect to sliding modes control and techniques stemming from infinite-dimensional systems, such as delays or partial differential equations. Our paper is illustrated by several computer simulations.

National audience; Recent techniques, which are of algebraic flavor, allow not only to prove the identifiability of parameters, like the free-flow speed and the critical density, which are of utmost importance for the control and the supervision of freeway traffic, but also to estimate them quite efficiently in real time. The significance of our approach for intelligent transportation systems is confirmed by numerous successful computer simulations.

International audience; We present for the longitudinal control of an electrical vehicle a "model-free'' control strategy, which is illustrated by convincing experimental results. The physical control is a coefficient rate of the maximal voltage of the battery. The chassis and the engine dynamical equations exhibit complex unknown parameters and/or neglected terms. The proposed ``intelligent'' PI controller, which utilizes new algebraic techniques for estimating derivatives of noisy signals, permits to bypass those parameter and model uncertainties, without the necessity of identifying them.

Operational calculus, differential algebra, noncommutative algebra and nonstandard analysis are the main mathematical tools.
