Discrete-time quasi-sliding mode control for input constrained systems

In this paper, a quasi-sliding mode control strategy for discrete-time uncertain systems with input constraints is proposed. The quasi-sliding mode controllers are designed based on the quality of the equivalent control, and the width of the quasi-sliding mode band is reduced effectively. Comparing with other published methods by simulations, this strategy guarantee better robustness, faster states convergence, and improved steady state accuracy of the system.
