基于转矩分配函数的开关磁阻电机转矩脉动抑制研究

Study on Torque Pulse Inhibition of Switching Reluctance Motor Based on Torque Distribution Function

传统开关磁阻电机转矩脉动抑制方法直接进行开关角寻优未对抑制区间进行划分,造成电机转矩脉动抑制效果较差。提出基于转矩分配函数的开关磁阻电机转矩脉动抑制研究。通过划分抑制区间,提高转矩的稳定性和可靠性,基于转矩分配函数进行开关角寻优,实现开关磁阻电机转矩脉动抑制。实验结果表明该方法转矩返回率较低,对于抑制转矩脉动具有一定的效果。

The traditional torque ripple suppression method for switched reluctance motors directly optimizes the switch angle without dividing the suppression interval,resulting in poor torque ripple suppression effect of the motor.Propose a study on torque ripple suppression of switched reluctance motors based on torque allocation function.By dividing the suppression interval,the stability and reliability of torque are improved,and the switching angle is optimized based on the torque allocation function to achieve torque ripple suppression of switched reluctance motors.The experimental results show that this method has a low torque return rate and has a certain effect on suppressing torque ripple.
