4. A Flexible Cloud-Based HIL Testing of Batteries for Various Electrified Vehicles

Author

Abstract

Power Hardware-In-the-loop (HIL) testing is increasing in the automotive industry for testing subsystems for new vehicles. Usually, the test is located in a unique place (stand-alone (local) HIL). The key-points for a vehicle manufacturer and subsystems suppliers are time and confidentiality. Using the cloud is a way to satisfy the both. Cloud model sharing is developed to spare time and cloud-based real-time simulation limits the access to the models to only certain variables. In this article, a cloud-based power HIL testing is proposed using a cloud of vehicle models. The Energetic Macroscopic Representation (EMR) formalism is used to organize all the models. It facilitates the interconnections between the simulated and power tested subsystems. Two new batteries are experimentally tested, one for an electric vehicle, the other one for a plug-in hybrid vehicle. The same cloud is used and the power test facilities are located in two different locations. This shows the flexibility of the method.

Abstract

When a finger touches an ultrasonic vibrating plate, a non sinusoidal contact force is produced. This force is denominated acoustical finger force. In this paper, a method is proposed, in order to observe its fundamental component in the context of a friction reduction haptic interface. A PCA (Principal Component is applied to the measured data, which will help evaluate the correlation between this measurem ent and the friction when sliding the finger. A linear model that predicts the friction coefficient is laid down and evaluated The interest of this study is to provide a mean to adapt the tactile feedback device control to each user, despite of the biomec hanical properties differences within each finger pad. This work has been carried out within the framework of the Mint Project of IRCICA (CNRS Service and Research Unit 3380

Abstract

Using piezoelectric actuators can reduce the bulk size of servomechanisms; they are thus very useful in avionics applications. However, mechanical overload on the shaft of a traveling-wave ultrasonic motor often results in the motor suddenly stalling. To avoid this drawback, one can increase the supply voltage or add a control loop in the rotating reference frame of the traveling wave. The consequences are extra power losses or lower dynamic performances. The proposed method combines the advantages of classical controls and controls in a rotating frame: Both stability and dynamic performances are obtained at low supply-voltage levels. Experimental runs are presented. Index Terms--Acoustic motors, motor drives, position control, rotating machine stability.

Abstract

In this paper, precise position control of a traveling-wave ultrasonic motor is achieved, avoiding the traditional drawbacks attributable to nonlinear torque generation, which are overshoot or slow response time. For that purpose, a behavior model control is proposed and presented. With this control law, a quick and precise response is obtained. In this paper, we present a position-control scheme of an inertial load. The guideline used for this control was a rotation of 90[degrees] in a response time of about 200 ms with a position error of 0.6 mrad, targeting a typical application for avionics. In this paper, a Shinsei USR30 is used, but the method can be applied to other ultrasonic motors. Index Terms--Causal modeling, control, piezoelectric, precision, ultrasonic.

Abstract

International audience; A realistic keyclick sensation is a serious challenge for haptic feedback since vibrotactile rendering faces the limitation of the absence of contact force as experienced on physical buttons. It has been shown that creating a keyclick sensation is possible with stepwise ultrasonic friction modulation. However, the intensity of the sensation is limited by the impedance of the fingertip and by the absence of a lateral force component external to the finger. In our study, we compare this technique to rendering with an ultrasonic travelling wave, which exerts a lateral force on the fingertip. For both techniques, participants were asked to report the detection (or not) of a keyclick during a forced choice one interval procedure. In experiment 1, participants could press the surface as many time as they wanted for a given trial. In experiment 2, they were constrained to press only once. The results show a lower perceptual threshold for travelling waves. Moreover, participants pressed less times per trial and exerted smaller normal force on the surface. The subjective quality of the sensation was found similar for both techniques. In general, haptic feedback based on travelling ultrasonic waves is promising for applications without lateral motion of the finger.

Abstract

International audience; Among human senses, touch is much less understood than hearing or sight. However, today, new emerging technologies are placing tactile interaction at the heart of the communication with smart devices (smartphones, tablets, …). Hence, studying the sense of touch is now very important, in order to better understand the mechanisms induced from the mechanical excitation of skin to the feeling experienced by a user. Also, being able to detect and measure tactile disabilities, and to propose rehabilitation is a challenge; otherwise, numerous people can drift away from these objects as they can't be used easily by them. In the paper, we present Dtact, a device which stimulates the finger pulp with a calibrated stimulation. It is designed to be used during experimental studies aiming at recording nerves and brain activity of a user touching its surface. It will be used to detect tactile disabilities, and perhaps some exercises could be programmed for the purpose of rehabilitation.

Abstract

International audience; We present a novel method to compare brain responses to identical tactile stimuli in active and passive touch. Using electroencephalography (EEG) to record steady-state evoked brain potentials (SS-EPs), our goal was to characterize the cortical activity related to the tactile exploration of a textured surface. For this purpose, we used a novel tactile display, which is able to produce tactile texture experiences using ultrasonic stationary waves to transiently modulate tangential friction between the finger and the display. Because the change in friction depends on the amplitude of the ultrasonic vibrations, modulation of ultrasonic vibration amplitude was used to periodically modulate friction at a frequency of 11 Hz, producing a tactile percept resembling that of a square-wave grating. After recording the exact motion of the fingertip and normal force used for each trial while one participant freely explored the surface (active touch condition), the same motion and normal force was reproduced by a high-precision robotic device with force feedback (passive touch condition). Frequency analysis of the recorded EEG signals showed that, for both active and passive touch conditions, the interactions between the fingertip and the plate elicited a robust SS-EP at 11 Hz, corresponding to the frequency of friction modulation, maximal over the parietal region contralateral to the stimulated finger. Our results suggest that the cortical activity related to active and passive touch can be characterized in humans by combining the recording of SS-EPs with an ultrasonic device generating a periodic tactile experience whose frequency is independent of finger movements.

Abstract

International audience; This paper presents a method for controlling the vibration amplitude of a tactile stimulator used to give the sensation to the fingertip that it touches a texture. The active surface of the stimulator is excited by an ultrasonic vibration frequency in order to modulate the friction coefficient with the fingertip. Due to the large size of the tactile display, two types of perturbations may affect the vibration amplitude which are the finger pressure and the temperature variation. We tackle these problems by coupling the control of the vibration amplitude and the tracking of the resonance frequency. This work is validated by plotting the vibration amplitude response with closed loop control and with a psychophysical test.

Abstract

International audience; This paper deals with an unidimensional analytical modelling of the vibratory behaviour of a rectangular beam excited by several piezoelectric ceramics glued on its lower face. The establishment of the equations of motion is guaranteed by the application of Hamilton’s principle. From this approach, it results an accurate knowledge on the mode shape in function of the geometry, the structure and the positions of the piezoelectric actuators. These cleverly chosen degrees of freedom consequently enable to promote peculiar mechanical vibratory mode, advantage experimentally validated. This approach deployed on a simple case falls within a general process of the surface tactile devices optimization. The planned applications use the reduction of the effective friction by the generation of an air film between the vibrating plate and the user’s finger by means of piezoelectric ceramics.

Abstract

International audience; Tactile stimulation is used in the rehabilitation of damage to the central or peripheral nervous system and in brain injury recovery. Tactile deficits of the hand are currently diagnosed through the evaluation of pain thresholds, spatial discrimination, vibration sensitivity and by using filaments or tuning forks, without truly established protocols. The global goal of the COSTaM project is to develop a tactile stimulator to identify tactile disorders and allow specific rehabilitation. The first step is to study the response of healthy individuals to complex textures in different ways : perceptive discrimination, study of friction and vibration between textures and the finger and the response of each kind of cutaneous mechanoreceptor. Three kinds of real textures have been chosen: relief, braking and fibrous. The use of a tactile stimulator, based on the modulation of the coefficient of friction with the finger, has been validated for the simulation of the braking descriptor.

Abstract

International audience; This paper describes the implementation and initial evaluation of active-type tactile displays in desktop environments. The first device comprises a stator of an ultrasonic motor supplied by only one channel. In this way, the motor twisted of its application do not induce movement but can create slipperiness on the stator's surface. This effect can be interpreted as squeeze film phenomenon and allow us to change indirectly the friction on the surface and to generate shear forces on the fingertip, which in turn creates interesting tactile effects. Moreover, if we add a position sensor, we can vary the signal spatially which gives the sensation of bumps/ridges. Then, based on the first device principle, another device is proposed in order to enable a free exploration of the surface following ergonomic requirements.

Abstract

Application of vibration in metal forming process has already shown numerous advantages in the past. It improves not only mechanical and surface properties of workpiece but the integration of vibration in metal forming process has also been helpful in the reduction of forming force required for the process. Majority of the work done before in this field is related to single vibration source vibration and its application in metal forming process. The aim of this work is to develop a mathematical model for multi vibration assisted forging process. The combination of multi mechanical vibrations generates a complicated movement of lower die without deforming it. This developed mathematical model proves that movement is basically in the form of progressive wave in the lower die thus resulting local surface movement. In reality this movement can be generated by the vibration given by multi piezoelectric actuators. Based on this mathematical model, simulations using finite element software Forge2011® have been performed to observe the presence of progressive wave in the workpiece. The simulations' kinematics confirms the existence of progressive wave in the workpiece. Simulation results demonstrate the effect of progressive wave to reduce the forging force, reduction of friction on the lower surface of die and hence improvement the forging process. Based on the developed mathematical model and simulation results, design proposition for multi vibration assisted forging process has been presented in this work. [ABSTRACT FROM AUTHOR]

Abstract

This paper presents the modeling of forging processes assisted by vibrations. A piezoelectric actuator is used to generate specific low-frequency vibration waveforms superimposed to the forging motion. Experimental results show a reduction of the forging load during upsetting tests. However, the appropriate waveforms and their influence on the forging load are still poorly understood. Moreover, the requirements of actuators and the design of the control should be known in advance. Therefore, there is a need for simulation to predict those issues. Due to the complexity of the interactions between the different components of the system, a complete model of the process is proposed. It is developed using an energetic macroscopic representation to preserve causality throughout the modeling. Simulation results are then compared with representative experimental results.

Abstract

Study of a wind-energy-conversion system (WECS) is a very attractive topic for students. The analysis of an entire WECS requires knowledge of different scientific fields, which are of interest for future engineers. In this paper, energetic macroscopic representation is used to describe a complete WECS. This synthetic graphical tool yields a natural decomposition of the studied WECS with respect to physical laws. Moreover, a control scheme is easily deduced from this description using inversion-based rules. Thus, maximum-power point-tracking strategies and drive controls can be defined. The simulation of the studied WECS is directly transposed to MATLAB-Simulink. Moreover, a hardware-in-the-loop simulation of the WECS is studied using an actual induction generator. and an electrical drive to simulate the wind turbine. This graphical methodology is used in the electrical engineering Masters degree at the University of Lille (France). [ABSTRACT FROM AUTHOR]

Abstract

Using piezoelectric actuators can reduce the bulk size of servomechanisms; they are thus very useful in avionics applications. However, mechanical overload on the shaft of a traveling-wave ultrasonic motor often results in the motor suddenly stalling. To avoid this drawback, one can increase the supply voltage or add a control loop in the rotating reference frame of the traveling wave. The consequences are extra power losses or lower dynamic performances. The proposed method combines the advantages of classical controls and controls in a rotating frame: Both stability and dynamic performances are obtained at low supply-voltage levels. Experimental runs are presented. [ABSTRACT FROM AUTHOR]
