Abstract :
This paper investigates the means to design a robust nonlinear controller for a class of nonlinear system with uncertainty and unknown parameter. A new design approach of optimization controller is proposed. The controller expression with undetermined parameters can be acquired by using adaptive backstepping and slide mode design idea, and the controller parameters are optimized on using genetic algorithm. By using controller proposed in this paper, not only the stability of the closed loop system can be acquired more easily but also the dynamic behavior of the system is well. Simulation results show that the controller is valid.
