Robust Control for Nonlinear Systems with Bounded Perturbation
|
Abstract:
This paper discusses the robust stabilization via state feedback for uncertain nonlinear systems. The uncertainty is described by gain bounded perturbation function on the state variables. The main result shows that a feedback control law can be obtained by constructing a positive definite Lyapunov like function, if the considered system is of robust minimum phase and its nominal system has relative degree one.
