描述了一种抑制 PWM（脉宽调制）逆变器驱动感应电机时产生的振荡的新颖控制方法。通过在逆变器输入电流的负电流分量的整个振荡周期中保持功率方向恒定来实现抑制。该周期仅由 PWM 信号的频率决定。由于它不受电机参数（例如极数或电机容量）的影响，因此控制系统中调节器的增益不必调整，即使该方法应用于各种感应电机驱动系统。实验证明，无论电机类型或速度如何，都可以抑制振荡。这种稳定控制适用于驱动各种类型电机的通用变频器。 >
A novel control method that suppresses oscillations generated when an induction motor is driven by PWM (pulse width modulated) inverters is described. The suppression is done by keeping the power direction constant throughout the period of oscillation of the negative current component of the inverter input current. This period is determined only by the frequency of the PWM signals. Because it is not affected by motor parameters, such as the number of poles or motor capacity, the gains of the regulator in the control system do not have to be adjusted, even if this method is applied to various kinds of induction motor drive systems. Experiments have proven that oscillations can be suppressed regardless of the motor type or speed. This stabilizing control is suitable for general-purpose inverters that drive various types of motors. >
