Abstract

This paper deals with adaptive stabilization problems for a class of stochastic nonlinear systems with input saturation. A dead zone based model is used to describe saturation phenomenon. A stochastic Lyapunov method is applied for systems in strict-feedback form driven by Wiener noises of unknown covariance. An adaptive controller is obtained which guarantees the global asymptotic stabilization in probability. Simulation results are provided to illustrate the effectiveness of the proposed approach.
