一种控制器与滤波器的协调优化设计方法

为了提高系统的信噪比,将系统滤波器引入过程控制系统,必定会产生某些不利因素,首先是系统模型阶次增高,其次是滤波器会产生相迟角。设计高阶且有滞后的控制系统是很困难的。一种可以方便地解决此类问题的方法是分离与协调方法,本文介绍其设计原理及仿真结果。

An optical design method of coordination between both controller and filter

In order to raise the signal to noise ratio and incorporate a system filter into a process control system, some unfavorable factors are sure to be produced. The first thing is that the system model order will become high, and then the filter in use will yield a phase angle. It is very difficult to design a high order and dead time control system. A separated and coordinated method is presented to solve these problems easily. The design principle and system simulation are also described in this paper.
