针对一般开关磁阻电动机直接转矩控制采用滞环控制所存在的较大转矩脉动的问题，结合空间矢量调制（ SVM）技术，提出一种基于SVM的开关磁阻电动机PID直接转矩控制的方法，转矩环采用PID控制，PID输出作为参考电压矢量，由于电压矢量与转矩近似成正比关系，故实现了转矩的连续控制。为了验证该方法的有效性，对开关磁阻电动机一般直接转矩控制及基于SVM的PID直接转矩控制进行了仿真，仿真结果表明基于SVM的PID直接转矩控制能够精确控制转矩，转矩脉动小于一般的直接转矩控制。
針對一般開關磁阻電動機直接轉矩控製採用滯環控製所存在的較大轉矩脈動的問題，結閤空間矢量調製（ SVM）技術，提齣一種基于SVM的開關磁阻電動機PID直接轉矩控製的方法，轉矩環採用PID控製，PID輸齣作為參攷電壓矢量，由于電壓矢量與轉矩近似成正比關繫，故實現瞭轉矩的連續控製。為瞭驗證該方法的有效性，對開關磁阻電動機一般直接轉矩控製及基于SVM的PID直接轉矩控製進行瞭倣真，倣真結果錶明基于SVM的PID直接轉矩控製能夠精確控製轉矩，轉矩脈動小于一般的直接轉矩控製。

Combining the space vector modulation technology to solve the bigger torque ripple problem of the conventional direct torque control with the hysteresis loop control in this paper .A direct torque PID control was presented of switched reluctance motor based on SVM ,which can control the torque continu-ously with the PID torque loop ,because torque is approximately proportionate to the voltage vector deter-mined by the torque PID controller .The simulation was accomplished to verify the validity of the proposed method of the conventional direct torque control and the direct torque PID control ,the simulation results showed that the direct torque PID control based on SVM can control the torque accurately ,torque ripple is less than the conventional direct torque control .
