Discrete time sliding mode control using multirate output feedback to reduce chattering

This paper presents a multirate output feedback based discrete time sliding mode for different reaching law. The proposed algorithm used past control input for switching function and output samples to design controller. It has been shown that chattering problem can be reduced by proper selection of the reaching law parameter. The performance and reliability of the proposal algorithm will be determined by performing extensive simulation works using simulink
