Abstract

The article proposes and substantiates a method for studying the dynamics of an asynchronous electric drives with frequency control from the input side of the signal for setting the speed of rotation of the electric motor. In this method, a constant speed reference signal is added to a harmonic variable frequency signal. The set of amplitude changes and phase shifts of velocity oscillations are the initial data for identifying the dynamics of the studied control method. The logic of this method is determined by the previously obtained nonlinear transfer function of the link that forms the mechanical moment in the asynchronous electric drive with frequency control. Experiments have shown the dynamic benefits of the drive with positive stator current feedback.

AED频率调节算法动态效率的实验识别方法

本文提出并证实了一种从设定电动机转速的信号输入侧进行频率控制的异步电力驱动器动力学研究的方法。在该方法中，将恒定速度参考信号添加到谐波可变频率信号。速度振荡的振幅变化和相移集合是用于识别所研究的控制方法的动力学的初始数据。该方法的逻辑由先前获得的链路的非线性传递函数确定，该非线性传递函数在具有频率控制的异步电驱动器中形成机械力矩。实验表明，具有正定子电流反馈的驱动器具有动态优势。
