Abstract

In this paper, basing on Lyapunov stability theory, a typical adaptive control system with dead zone is firstly proposed for a class of nonlinear plants with bounded disturbance. It is shown that a larger state tracking error norm is given when a conservative dead zone value is set to achieve a stable adaptive control scheme for the plant subjected to a bounded disturbance. To solve this problem, a modified adaptive control with dead zone scheme is proposed. The proposed adaptive control scheme is proved to be stable and the state tracking error norm can be reduced.Finally, the performance of the modified robust adaptive control with dead zone is shown by some simulation results.
