SR machines have a significant torque ripple, especially when operated in single-pulse voltagecontrolmode.
SR机器有重大扭矩波纹，特别是当经营在唯一脉冲电压控制方式。

According to the characteristic of the control loop, simple voltagecontrolmode and basic PI compensation are employed to ensure the stability of the converter.
Another kind of the voltagecontrolmode, through the high and low voltage on motor speed control, motor feedback signal through the drive to the numerical control system feedback position control.
