【摘要】 本文对采用零矢量调制的感应电机直接转矩控制方法及其实现进行了研究。在分析常规直接转矩控制方法引起转矩脉动原因基础上,构造了一个引入零矢量调制的转矩脉动最小化算法,并在一个基于DSP控制的实验系统中完成了实验研究。实验结果表明,此方法不仅能使电机控制保持良好的动态性能,同时能有能效减少稳态时转矩脉动。更多还原

【Abstract】 In this paper, a modified DTC method for induction machine is investigated using zero-vector modulation. By analyzing the principle of torque ripple,an arithmetic of minimizing torque ripple is proposed,along with the experimental results of a practical control system based on DSP. Experimental result verifies that the presented method could achieve satisfied dynamic performance and reduce torque ripple effectively.更多还原
