Shunt active power filter based on a novel sliding mode backstepping control for three-phase three-wire system

Abstract

This paper presents a global fast terminal sliding mode (GFTSM) control based on back stepping design for active power filter(APF). Power system is a typical nonlinear system. Its mathematic model can be reduced order by back stepping method. Power system is decomposed into low-level subsystems until finalizing the design of the control law. The System's stability is ensured by Lyapunov framework. The sliding mode control is added into back stepping control to expand the application scope of control. The slid…
