Abstract :
This paper presents the analysis of a current control system to PMSG in overmodulation region. A detailed review of the space vector modulation in over-modulation region is initially presented. Then, an anti-windup method for current controller of PMSG is proposed. The equilibrium points of the closed loop system are calculated and an estimation of the region of operation with guaranteed stability is determined using linear matrix inequalities. Simulation results are presented and illustrate suitable closed loop performance.
