An optimization algorithm for robust state-feedback eigenstructure assignment in descriptor linear systems with parameter perturbations is given 摘要針對具有參數(shù)攝動廣義線性系統(tǒng)的魯棒狀態(tài)反饋特征結構配置問題,提出了一種優(yōu)化算法。
The decoupling control system designed on this theory is not robust . 3 . the decoupling control theory based on eigenstructure assignment is studied, also includes two cases : full state feedback and output feedback 3、進行了線性定常系統(tǒng)基于特征結構配置的解耦控制研究,分別考慮了全狀態(tài)反饋和輸出反饋兩種情況。
These decoupling theories are : the decoupling control theory which was firstly put forward by morgan; the decoupling control theory based on eigenstructure assignment and the decoupling theory based on h control 這三種解耦理論分別是:基于morgan問題的解耦控制,基于特征結構配置的解耦控制和基于h_的解耦控制理論。

First, the thesis introduces the definitions and the attributes of the higher-order statistics . it is insensitive to additive gaussian noise ( white or colored ), which is what we base on to doa problems . then two doa estimation algorithms based on higher-order statistics are presented, one is that forming cumulant matrix pencil used in esprit to estimate doa problems, the other is spectrum estimation method for doa estimation based on the eigenstructure analysis of the fourth-order cumulant, and comparing the effects of the estimation to conventional covariance-based doa algorithms " 論文首先對高階統(tǒng)計量的定義和性質作了介紹,特別指出了高階統(tǒng)計量對加性高斯噪聲(白色或有色)不敏感,這是我們利用它進行波達方向估計的理論依據(jù),然后文中提出了兩種基于高階統(tǒng)計量的波達方向估計方法,一種是利用子空間旋轉不變技術構造四階累積量矩陣進行估計的方法,另一種是基于四階累積量陣特征分解的空間譜估計測向方法,并將它們的估計效果與傳統(tǒng)協(xié)方差方法的效果進行比較。
The margin is evaluated by the minimum singular value of return deference matrix of system . by analyzing and comparing those three decoupling methods, we come into two conclusions : one is that decoupling performance and stability robustness are contradictory, the other is the nonrobust decoupling control method based on morgan's theory and which based on eigenstructure assignment theory is equivalent 對三種解耦方法的穩(wěn)定裕度進行了分析和比較,井得出了相應的結論:結論一是解耦性與魯棒性是一對矛盾,結論二是基于organ問題的解耦方法與基于特征結構配置的非魯棒解耦方法是等效的。
