A method to design digital preview sliding mode servo system is proposed. Sliding mode regulator theory is applied to an augmented error system in which obtainable desired signals or disturbance signals are added. The equivalent control which make the states of error system stay on the switching surface is employed. Then, the sliding mode controller is designed. Preview sliding mode servo system by using this control has both merits of the preview control and the sliding mode control. The computer experiments are given to illustrate the effectiveness of the proposed deign method.
