The dSPACE is the hardware plat for the real-time control system based on Matlab/Simulink, which has high reliability and rapid real-time. The decoupling real-time simulating method of discrete event excited converter system and continuous time dual stator-winding generator system based on dSPACE DS1104 is proposed. The real-time control modern of novel dual stator-winding generator based on DS1104 is setup. The real-time simulating researches including voltage build up, variable speed of dual stator-winding induction generator are presented.
