Full textThe objective of our research is to analyze the subject's interactions traces using the Tactos device, which comprises a stylus, a graphic tablet and a tactile stimulators connected to a computer equipped with an application software. The principle of this interface is to activate the stimulators when the cursor receptor field controlled by stylus crosses the virtual form that the subjects must perceive. The goal of our analysis is to define descriptors which categorize and differentiate the trajectories produced by the subjects, and to use these descriptors in order to model the various spontaneously elaborated perceptive strategies. To operate this analysis, we had resort to several mathematical tool descriptions, in particular the Fourier, and to various modelling methods. The results, by the means of the models tested and validated, make it possible to differentiate indeed a certain number of strategies employed by the human subjects. These models could be integrated into the interface; thereafter the users can have a return on the nature of their explorations, which would contribute to the training and the appropriation of the interface

Full textThis work presents a new design approach for trajectory tracking control of robot manipulators. In spite of the rich literature in the field, the problem has not yet been addressed adequately due to the lack of an effective control design. In general, it is difficult to adopt design to achieve high-precision tracking control due to the uncertainties in practical applications, such as friction forces, external disturbances and parameter variations. In order to cope this problem, we propose first control with H∞ performance to reference trajectory tracking control of two degrees of freedom robot. Secondly, we propose a new design framework with parametric uncertainties and unknown disturbances by using the feedback and the feedforward controllers. Using the descriptor Takagi-Sugeno systems, the design goal is to achieve a guaranteed tracking performance while signicantly reducing the numerical complexity of the designed controller through a robust control scheme. Based on Lyapunov stability theory, the control design is formulated as an LMI (linear matrix inequality) optimization problem. Simulation results carried out with a high-fidelity serial manipulator model embedded in the Simscape MultibodyTM environment of MatlabR clearly demonstrate the effectiveness of the proposed method by comparing with PID controller and computed torque controller

Full textThis study was supported by the “Région Chamapgne Ardenne” within the framework of the CPER “Sys-Rééduc” project which aims to design and control a new lower limb rehabilitation device. In the first chapter, a brief state of the art of rehabilitation techniques is done and the interest of developing a closed muscular chain (CMC) device is pointed out. Indeed, CMC rehabilitation techniques have interesting skills for the recovery of motor functions and muscle strengthening of the lower limbs as well as ensuring the dynamic joint equilibrium. Then, in the second chapter, the kinematical concept of the new rehabilitation device in CMC and its control structure is proposed. The third chapter deals with the continues level of the control structure. Its aim is to ensure the stability and the trajectory tracking of the mechanical system whatever the patient's effect to the machine is. Thus, a Takagi-Sugeno model based tracking control law design is proposed for a class of nonlinear descriptors. The stability conditions are written into LMIs based on the second Lyapunov method. The fourth chapter deals with the proposed trajectory generator allowing the voluntary control of the system by the patient. The proposed control structure is then validated in simulation on the new Sys-Rééduc concept and, since it is not available for a real time implementation yet, an experimental validation is proposed on an open muscular chain rehabilitation device available at the CReSTIC
