Based on a general parametric eigenstructure assignment result proposed for descriptor linear systems via proportional plus partial derivative state feedback and a result for generalized eigenvalue sensitivity problem of matrix pairs, parametric representation of the closed-loop eigenvalue sensitivities to the perturbed elements in the open-loop system matrices is obtained. An effective algorithm for eigenvalue assignment with minimum sensitivity in descriptor linear systems via proportional plus partial derivative state feedback is then proposed.

摘要基于廣義線性系統(tǒng)比例與部分狀態(tài)導數反饋參數化特征結構配置結果和矩陣對廣義特征值靈敏度結果，得到了關于開環(huán)系統(tǒng)矩陣中攝動元素的閉環(huán)特征值靈敏度的參數表達式，并在此基礎上提出了廣義線性系統(tǒng)比例與部分狀態(tài)導數反饋最小靈敏度特征值配置的有效算法。
