摘　　要：介绍一种运用单片微机进行磁通轨迹控制的电压型GTO逆变器变频调速系统.磁通轨迹法是通过对异步机磁链的直接控制,使其轨迹近似为园,尤其在低频时轨迹更近似为园,从而使系统噪声小、无低频转矩脉动现象、具有恒磁通调速特性.The authors introduce a voltage-source GTO inverter VVVF system with flux linkage locus controlled by single-ship microcomputer. Flux linkage locus method is to make flux linkage locus approach a circle through direct control of asynchronous motor flux linkage,specially at low frequency, so that low noise,no low frequency torque ripple and constant flux speed adjustment characteristics can be obtained.
