New robust control schemes linking linear and sliding mode approaches

Abstract : This work deals with the design of control laws for nonlinear, uncertain and perturbed systems based on sliding mode control and linear state feedback. Sliding mode control is known for its robustness versus perturbations and uncertainties as well as high accuracy tracking; however, it is high energy consuming. The linear state feedback is known to be a smooth control and low energy consuming, but it is highly sensitive to perturbations and uncertainties. The first objective of this thesis is the development of control laws that have the advantages of both sliding mode control (robustness and accuracy) and linear state feedback (low energy consumption). The second objective is to show the applicability of the proposed methods to real physical systems, notably the LS2N electropneumatic bench. Applications are also made on a wind system physical systems, notably the LS2N electropneumatic bench. Applications are also made on a wind system.
