| 摘 要： | 在进行大范围控制参数寻优时，往往会遇到计算量过大的问题。为了减小寻优的计算量，提高程序运行的效率，本文基于衰减频率特性法，针对一阶环节加延时环节对象和任意不含延时环节对象，给出了一种判定PI控制器稳定参数的计算机实现方法。仿真实验表明：此判定方法使得计算量大大减小，寻优时间大大缩短，且易于计算机实现。

| Abstract: | Huge calculation appears when we carry out an optimization for control parameters gain. In order to reduce calculated amount and improve the efficiency of the program aiming at optimization, a way to judge the stable control parameter of PI controller for the arbitrary order system without dead time and first-order plus dead-time system, based on attenuated frequency characteristic, is presented in this paper. This method is easy to be carried out by the computer and reduce the calculated amount greatly. This point is proved by plenty of examples. |
