【摘要】 针对基于直接转矩控制的感应电动机在低速运转时存在较大的转矩脉动问题,该文提出一种新的控制方法。该方法在传统直接转矩控制的基础上,引入一个转矩脉动最小化控制器,以使感应电动机的转矩脉动达到最小。实验结果表明该方法能够有效地解决转矩脉动问题。更多还原

【Abstract】 Due to the large torque ripple of inductance motor based on direct torque control, especially at a low speed, this paper proposes a new control strategy. On the basis of conventional direct torque control, a torque ripple minimum controller is introduced in the strategy in order to decrease torque ripple. The simulation shows that it can get good torque performance.更多还原
