Abstract
This paper presents the design method of full digital controller of three-phase inverter system. Two coupling terms are analyzed by RGA to make SISO system. Full digital controller includes digital plant modeling, digital controller design, digital simulation and experiment using DSP. Digital plant is modeled by zero-order hold and z-transform. Digital controller is designed as RST structure without additional zero and the pole-placement method was used to find controller gains. Also, the designed controller is simulated by PSiM DLL and experimented by TMS320VC33. The simulation and experiment results show good performance like as well tracking and well regulation.
