Abstract :
This paper presents a decoupling IPD voltage control for three-phase DC/AC inverter. Though most of three-phase inverter system for UPS or stand alone renewable energy system have been analyzed by using DQ model and controlled with IPD controller. For the simplification of this DQ model coupled each other, DQ decoupling technique is proposed firstly and so the MIMO system can be changed to SISO system. Secondary, the CRA based design procedure for IPD controller is presented and it satisfies the specified time response and overshoot of the controller, of which parameters are determined practically by trial and error method. Finally, the performance of this proposed algorithm is verified through PSiM simulation.
