Robust regulation of time-delay processes using sliding mode control

This paper presents a sliding mode controller for the regulation of processes with time-delay. Sliding mode control is examined from the perspective of obtaining stable and robust tracking of an arbitrary time-delay process control systems driven by a certain class of bounded errors, nonlinearities and disturbances. Delay ahead predictor is used for state estimation and correction term from the measured process output. The sliding mode controller is synthesized to account for matched uncertainty and unmeasurable disturbance. In particular, tracking of plants states are shown for time delay processes.
