釆用一个二阶系统的模型代替真实系统，其差分方程表达式为： 将此系统在计算机上仿真，输入信号u(k) 是幅值为1 的PRBS 信号，噪声e(k) 是（0，1）的正态分布序列，它的方差是可以调整的。这个系统的输出釆样值z (k) 与u (k) 作为已知数据，采用最小二乘法估计这个系统的参数。 (Preclude the use of a second-order system model instead of the real system, the differential equation expression: this system on a computer simulation, the input signal u (k) is the amplitude of the PRBS signal, and the noise e (k) (0 , 1) the normal distribution of sequence, its variance can be adjusted. The output of this system the Bian samples z (k) and u (k) as known data, the method of least squares to estimate the parameters of this system.)
