鲁棒过程控制系统的设计方法及其CAD程序

A DESIGN METHOD OF ROBUST PROCESS CONTROL AND ITS CAD PROGRAM

过程控制中常用的二阶加纯滞后模型往往具有多线性相关的参数摄动形式，本文找到了计算这类系统的闭环鲁棒稳定裕度的简便方法。以此为基础，形成了满足指定鲁棒稳定裕度的鲁棒过程控制系统的设计方法，并给出了ＣＡＤ程序框图。按此框图编程容易，勿须借助任何软件包和工具箱。

The second-order system with time delay model used in a process control tends to have multi-linearly dependent parametric perturbations.This paper discussses a convenient way to calculate the closed-loop robust stability margin of such systems.Based on its,a design method of robust process Control systems is developed which satisfies the appointed robust stability margin.In addition,a framework of the corresponding CAD Program is also offered which makes programming very easily and need not any software box or tool box.
