摘要
基于无位置传感器无刷直流电动机反电势法的控制原理,根据有源滤波器理论,设计了采用二阶巴特沃斯有源低通滤波器的转子位置检测电路。并详细介绍了有源滤波器的结构、阶数和参数选择方法,在此基础上,对所设计的位置检测电路进行了仿真分析和实验研究。
According to the operation principle of the back EMF method of the sensorless brushless DC motor drive and design theory of active filter,the rotor position detection circuit of brushless DC motor was designed,in which the second - order active Butterworth low pass filter was used. How to choose the structure, the order and the parameters of the active filter were suggested in this paper, and the simulation and experiment results were also given.
