摘要
PID控制、最少拍控制均存在对系统参数敏感的问题,对于水轮发电机组具有参数时变性和非最小相位特性这样的系统,上述2种控制都难以达到满意的控制效果,但通过对PID控制过程的数据挖掘,用MATLAB中的regress函数可得到控制器的线性解析式,这个多项式方程包含了PID控制规律,但又具有对系统参数不敏感的特点,应用于水轮发电机组调速系统表现出了很强的鲁棒性。
The PID control and the minimum control are both sensitive to system parameters.For a system as the hydro-generating unit with a parameter variability and non-minimum phase,the above-mentioned two kinds of control are difficult to achieve satisfactory control performance.But based on PID control process of data mining,using the regress function in MATLAB can obtain the linear analytical formula of the controller.This polynomial equation contains a PID control law as well as the characteristics of not sensitive to the system parameters,and has shown strong robustness when applied in the speed control system of hydro-generating unit.
