摘要
针对感应电动机直接转矩控制低速时转矩脉动大的问题,提出了一种改进的转矩预测法,仿真结果表明,该方法能有效地减小转矩脉动、改善定子磁链和电流波形,提高了起动的快速性,并减少了开关次数。
To reduce the low speed torque ripple of induction motor based on direct torque control（DTC）,a new control strategy-improved torque predict was proposed.The simulation showed that it can reduce the torque ripple,improve the waveform of stator flux and current,make the start of motor more fast and reduce the switch times.
