Abstract:
 iming at realization of multiphase motor unified SVPWM modulation and the realization ofmultiphase motor full-order observer sensorless vector control,based on traditional three phases motor ze-ro sequence voltage injection SPWM to achieve SVPWM modulation,derivation of multiphase motor uni-fied SVPWM and multiphase motor sensorless vector control was proposed. Taking the five phases asyn-chronous motor as an example,the percentage of SVPWM voltage utilization in the zero-sequence voltageinjection method was studied. The five-phase asynchronous motor was carried out that based on the sen-sorless vector control of the full order observer. The validity of proposed method was verified on five pha-ses asynchronous motor experimental platform. The experimental results show that the proposed unifiedSVPWM modulation method can improve the voltage utilization and optimize the harmonic performance. Uniform multiphase motor full-order observer sensorless vector control can achieve multiphase motor sen-sorless control,
reduce system cost and improve system reliability.
