Abstract :
In this paper, the control strategy combining an improved discrete-reaching law with equivalent control for uncertain discrete-time systems is present. The system not only has an advantage of strong robustness in variable structure control, but also avoids the chattering phenomenon. Furthermore, by incorporating an integral control, the stable-state precision is enhanced and the system exhibits excellent control characteristics. Simulation results illustrate the effectiveness of the method.
