Abstract

Presents two reaching laws of sliding mode for discrete-time variable structure control systems to solve the problem in designing the system control input. Considering the system control input is restricted, the reaching laws proposed in this paper adopt the approach angle and the distance to the sliding surface to regulate the system control input properly. By applying the proposed reaching laws of sliding mode to discrete-time variable structure control systems, the stability of the origin can be ensured, the dynamic performance of the system movement is improved. Finally two simulation examples are given to show the effectiveness of the two reaching laws proposed.
