Sliding mode control(SMC)becomes a common tool in designing robust nonlinear control systems,due to its inhe-rent characteristics such as insensitivity to system uncertainties and fast dynamic response.Two modes are involved in the SMC operation,namely reaching mode and sliding mode.In the reaching mode,the system state is forced to reach the sliding surface in a finite time.The major drawback of the SMC ap-proach is the occurrence of chattering in the sliding mode,which is undesirable in most applications.Generally,the trade-off between chattering reduction and fast reaching time must be considered in the conventional SMC design.This paper pro-poses SMC design with a novel reaching law called the expo-nential rate reaching law(ERRL)to reduce chattering,and the control structure of the converter is designed based on the multi-input SMC that is applied to a three-phase AC/DC power con-verter.The simulation and experimental results show the effect-iveness of the proposed technique.
