说明：  BLDCM的simulink模型，电流、转速双闭环控制的无刷直流电动机系统，电机模块是自己封装而成的不是用的永磁同步电动机或者自带的BLDCM，所涉及的三个程序也有展示。(The model of BLDCM, the BLDCM system with double closed-loop control of current and speed,and the motor module is a self packaged permanent magnet synchronous motor or BLDCM, and the three programs involved are also shown.)

说明：  the linear ARX model as shown below [12] is used to represent the input and the output data for the system. This ARX model is utilized for both Least Square (LS) and Recursive Least Square (RLS) algorithms. It is one of the simplest statistical methods for system identification used to find the transfer function for the model. The equations given by [15]: Y=φβ+ξ (7) β=〖(φ^T φ)〗^(-1) φ^T Y (8) where Y is the predicted output. φ is includes actual input and output parameters. β is includes parameters to be estimated.
