摘要:由矩阵变换器驱动的异步电机直接转矩控制(DTC)会导致较大的转矩脉动,只适用于调速要求不高的场合。为了减小转矩脉动,提出了一种模糊控制方法,采用模糊控制器来优化选择电压矢量。MATLAB仿真结果显示直接转矩模糊控制(DTFC)比传统的DTC转矩脉动小,磁链和转矩的综合性能都有所改善,证明了该方法的有效性。
Direct torque control of asynchronous motor fed by matrix converter, causes the larger torque ripples, and it only be used for the general speed-controlling requirement. To solve this problem, a fuzzy control method was proposed to optimize the choice of voltage vector. Simulation results showed that the new method leads to the lower torque ripples and the better flux trajectory. The combination performances of flux linkage and torque were improved, which proved the validity of this method.
