采用经典辨识——脉冲响应辨识系统的传递函数，文件以函数形式编写主要有3个参数：采样频率、系统阶次、噪声幅值(推荐参数分别为0.1、3、0.1)-Classical identificationThe—— pulse response identification to identify transfer function of the system. The file was written in function form mainly with 3 parameters: the sampling frequency, the order of the system, the noise amplitude (recommended parameters were 0.1, 3, 0.1)
