摘　　要：为保证转子磁链定向准确,提出了一种在线校正转子磁链角的方法。通过检测空间电压矢量PWM中的零电压矢量期间相电流的变化量,计算得到转子磁链的准确角度,经调节器在线调节转差角频率大小,从而校正转子磁链角,达到了提高电机控制性能的目的。通过试验验证了理论的正确性和方法的有效性。In order to ensure the orientation accuracy of rotor flux,a method of on-line correction of rotor flux linkage angle was proposed. By measuring the variation of phase current during zero voltage vector in space voltage vector PWM,the accurate angle of rotor flux could be calculated. The regulator adjusts the frequency of the slip angle online to correct the rotor flux angle so as to improve the motor control performance. The correctness of the theory and the validity of the method were verified through experiments.
