Abstract

Though continuous-time sliding mode control has a variety of desirable properties, its discrete-time counterpart does not guarantee the same performance. This is due to the fact that most of the discrete-time sliding mode control algorithms are based on reaching laws that are only approximations of continuous-time reaching laws and thus may not give a performance close to continuous-time sliding mode control. This paper presents a method of multirate output feedback based discrete-time control design which guarantees the closest possible performance for a pre-designed continuous-time sliding mode control algorithm
