Abstract
This paper suggests a fractional-order terminal sliding mode control (FO-TSMC) method for the output voltage regulation of a DC-DC Buck (Step-Down) converter influenced by disturbances, such as the changes of input voltage and load resistance. A this kind of a new fractional sliding surface is designed to avoid the drawback on integer-order (IO) terminal sliding mode control (IO-TSMC) method and guarantee the converter attain stable-state readily without chattering even if it undergoes arbitrary random disturbances. The proposed FOTSMC controller’s performance is compared against to both IOTSMC and traditional SMC control approaches. Computer simulation results display that the novel FO-TSMC approach results in evenhanded output voltage control under different load situations and wide input voltage changes.
