Abstract :
This paper presents a new approach to the discrete-time sliding mode control design based on the reaching law approach. A new discrete reaching law, which is stable at the origin, is proposed. Also, an algorithm for uncertainty estimation is developed. The proposed algorithm is applied to the control of a DC servo system. Simulation results show that the proposed controller can track a desired position signal well whether the uncertainties are present or not.
