線性多變數系統之計算機輔助解耦控制器設計

Abstract

本論文是針對一個線性多變數回授控制系統的計算機輔助設計軟體CADEC ，提出改善的方法。主要完成改良的部分包括：(I)計算副程式的修改， 如計算有理矩陣的反矩陣的運算法則，(II)最佳化部分的運算法則的全部 更新，以及在選取解耦控制器參數時，引進切換執行最佳化次序的技巧。 一些設計的例子顯示，上述技巧在面對多變數系統時，的確發生它的效用 ，並比較能照顧每個輸出結果。 In this thesis, we present some improvement to CADEC which is a computer-aideddecoupling controller design package for linear time-invariant square MIMOplants under unity-feedback configuration. The improvement done to CADECsoftware includes (I) modifications of the related algorithms and subroutinesfor computing the inverse of a rational matrix, and (II)the replacement of theoriginal optimization algorithm by a new one and the sequence of optimization is somewhat altered, that is, we carry out only oneiteration of every channel by turns in the course of optimization. As several design examples show, thisimproved CADEC usually gives better controllers especially for MIMO plants.
