Design of Fractional Order based Super Twisting Algorithm for BLDC motor

Abstract

This paper presents a chattering free fractional order sliding mode controller known as Fractional Order based Super Twisting Algorithm (FOSTA) proposed for BLDC motor. An analysis of second-order sliding-mode algorithms, specially of super-twisting algorithm is performed. Simulations are performed under various operating modes and performance of the controller tested on the dynamic model of BLDC motor using matlab-simulink. The performance of the FSOSMC compared to conventional PI controller.
