无刷直流电机调速系统仿真模型，霍尔传感器提供位置信号，调压调速-Brushless DC motor speed control system simulation model

七阶反对称滤波器，滤除低频和直流分量信号-The seven order anti-symmetric filter, filter out low frequency and dc component of the signal

带通滤波器，在信号处理时滤除直流分量和高频噪声，参数设置见程序说明。(The bandpass filter is used to filter the DC component and the high frequency noise in the signal processing. The parameter setting is explained by the program.)
