Abstract

This paper presents a modeling analysis of a nonlinear control strategy for a three-phase multilevel Advanced Static Compensator (ASVC). The nonlinear state-space model of the multilevel ASVC is obtained from the DQ0 reference frame. The input/output feedback linearization is then applied and the state feedback linearization control law is obtained. The model that was obtained was linearized and decoupled in two independent subsystems. The stabilizing controllers were designed based on the linear method. The simulation analysis was performed by MATLAB. The system performance was tested through a sudden change of the load from inductive to capacitive mode.
