基于INA设计方法的多变量PID控制器设计方法

The Design Method for Multivariable PID Controller Based on INA Method

在查阅总结大量相关文献的基础上,本文提出了一种基于逆Nyquist阵列(INA)设计方法的多变量控制器设计方法。在简要介绍了设计方法的理论基础和相关概念(极限点以及极限增益和极限频率)的基础上,以TITO多变量控制系统为例,简述设计思路,并给出其推导过程及其设计步骤;并借助仿真实验,与文献[8]所提出的设计方法进行了一系列的对比仿真实验,并给出了相关的分析和结论。

A design method of the multivariable PID controller based on Inverse Nyquist Array method is proposed based on reading plenty of literatures in this paper.The theoretical basis and related concepts （ultimate point,ultimate gain and ultimate frequency） of this design method is launched firstly.Take TITO multiloop sytem for example,the design methodology is introduced in detail on the basis of brief introduction of the theoretical basis and related concepts （ultimate point,ultimate gain and ultimate frequency）.At the same time,a series of comparative simulation experiments between this proposed design method and the design method proposed by [8] are given with related analysis and conclusion.
