常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)

验证可用，基于欧几里得距离的聚类分析，小波包分析提取振动信号中的特征频率。( Verification is available, Clustering analysis based on Euclidean distance, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  使用最小二乘法对永磁同步电机进行参数辨识，在simulink中搭建了永磁同步电机模型，然后使用s函数写了最小二乘法。(Use the least square method to identify the parameters of the permanent magnet synchronous motor, build a permanent magnet synchronous motor model in simulink, and then use the s function to write the least square method.)
