Abstract :
A simple sliding mode control is presented for the robust stabilization of input-delay systems with mismatched uncertainties and external disturbances. The proposed strategy includes a state predictor to compensate for the input delay of the system. A robust sliding mode control strategy is derived to overcome the effect of uncertainties. Based on Lyapunov stability theorem, the behavior and conditions for existence of the sliding mode under different uncertainties are studied in detail. A basic guideline is given for design of the sliding mode plane.
