摘要

This paper presents a chattering-free sliding mode control with unidirectional auxiliary surfaces (UAS-SMC) for nonlinear system with state constraints. In contrast to existing chattering-free sliding mode control (SMC) methods, the proposed strategy shows another way to eliminate the chattering phenomenon. Moreover, the positively invariant set in UAS-SMC is used to constrain the system states. Stability analysis is provided based on Lyapunov stability theory. Finally, a numerical example is given to show the benefits and properties of the proposed algorithm.
