Abstract

This paper presents a novel current control method for three-phase APF based on switched affine system quadratic stability. In this paper, three-phase APF is modeled as switched affine system. The three-phase grid voltages are divided into 12 regions, each region has chosen a combination of switching subsystems according to the condition for quadratic stability. By selecting the common Lyapunov function and designing the switching rules, the quadratic stability of a given switched equilibrium is ensured with switching. The proposed approach can improve dynamic response of the control system and reduce the operation switching frequency.
