应用最小二乘法设计的自校正调节器抗干扰能力差。其原因在于离差平方和作为目标函数进行参数估计,得到的模型稳定性差。离差绝对值和作为目标函数,得到的模型具有高拟合度和稳定性。本文给出了应用离差绝对值和作为目标函数设计模拟程度高、稳定性好的自校正调节器的算法。
Self-tuning regulator designed by least square method has poor anti-interference ability. The reason is that the square sum of the deviations is used as the objective function to estimate the parameters, and the obtained model has poor stability. The absolute value of the deviation and as the objective function, the model obtained with high fitness and stability. This paper presents an algorithm that uses the absolute value of the deviation and as a target function to design a self-tuning regulator with high degree of simulation and good stability.
