The structure for dual redundant permanent magnet synchronous motor (PMSM) was analyzed. Based on the sine pulse-width modulation (SPWM) and field oriented control (FOC) algorithm, a novel control method of the DR-SVPWM for dual redundant PMSM was presented. Based on the mathematic model of PMSM, a servo-model of dual redundant PMSM was established used the S-function and the algorithm of DR-SVPWM in MATLAB-Simulink. Via experiment, the results of phase current waveform of dual redundant PMSM were drawn and the dynamic response behavior of the motor driven by the method of DRSVPWM was analyzed. The results of the simulation and experiment verified that the DR-SVPWM method could simplify the control system of dual redundant PMSM and has a better control stability.
