Contribution à la commande robuste des systèmes non linéaires

Abstract

This work is based on the design of robust control of the buck DC-DC converter, with a study and choice of optimization evolutionary technique. This is a first step in evaluating the state of the art two robust control: a sliding mode control and synergetic control, and developing algorithms for control of a nonlinear system (converter) in a second phase. The synthesis of controllers generally results in a theoretically achievable convergence after an infinite time, it is proposed to accelerate the convergence that is to say a finite time approach among others. The parameters of the control signal produced will then optimized by an evolutionary approach (PSO).
