The design of sliding mode controller applied to servo systems is usually made on the basis of continu- ous systems, so sampling period seriously affects the systems performance. The paper presents a discrete sliding mode control strategy for a single-input single - output discrete system, the condition of existence of a sliding mode is given. A DC PWM servo system is controlled by this kind of discrete sliding mode control strategy. The result of simulation shows that discrete sliding mode control makes systems better performance.
