Sliding mode control design for robust regulation of time-delay processes

Abstract

This paper presents a new method for the robust control of time-delay processes using sliding mode control. In this approach an identified second-order-plus-deadtime model and state predictor are used for the sliding mode controller synthesis. To ensure the stability, the tuning parameters of switching control law are derived from the reachability condition. To test the applicability of the proposed approach, it was verified on processes having varying dynamics with deadtime. Simulations show that the proposed method is able to provide promising results compared to existing methods.
