基于矢量控制的异步电机速度检测方法的研究

Based on the Induction Motor Vector Control Method of Speed Detection

基于矢量控制理论设计的变频器控制系统性能的优劣,取决于系统对电流和速度的控制,其中主要包括输出电流的检测和速度反馈信号的检测。在本文中,针对有速度传感器系统和无速度传感器系统两种情况,对异步电机速度反馈信号检测的方法进行探讨。

Vector control theory based on the design of the inverter control system penormance advantages and disadvantages, depending on the system to current and speed control, which mainly include the detection of output current and speed feedback signal detection. In this article, the speed of induction motor speed feedback signal detection methods were discussed on two cases： no speed sensor systems and sensor systems.
