More general quadratic constraints and entropy constrains of the density programming will be dealt with in this article . the two problems are widely applied in information theory , statistical mechanics , insurance business and game theory 本文討論比mdi問題更普遍的帶有二次約束和熵密度約束的廣義熵密度規劃問題,這兩類問題在信息論、統計力學、對策論和保險業中有著廣泛的應用。
The stability of the feedback interconnection of a linear stable system and a bounded perturbation is studied in time domain in this paper . it s shown how a complex system can be characterized by integral quadratic constraints . and the iqc s theory in the time domain is given . for such model , a sufficient condition for the stability of the feedback interconnection is obtained , in some cases , this condition is also necessary . as the applications of the result in this paper , the problem of absolute stability is considered , then the timevarying circle criterion and other stability criteria are given 在時域內研究了由一個穩定的線性系統和一個有界因果系統所構成的反饋內聯系統的輸入輸出穩定性問題,給出了時域內的iqc的理論框架,得到了判定反饋內聯系統穩定性的一些判據,同時也得出了一些必要條件。最后,作為前面結果的一個應用,將所得的結果應用到絕對穩定性問題中,得到了時變的圓判據和其他的一些穩定性判據。
The stability perturbation bounds of a single - input - single - output system with both parametric and dynamic uncertainties is studied . the parametric uncertainties of the systems are described by interval perturbation mode , and the dynamic uncertainties are characterized by an integral quadratic constraint . based on the concepts of the minkowski functional , the problem of stability perturbation bounds is discussed , and for different uncertainty structures of the systems , the infinite stability checking problem of the mixed uncertain system can be converted to finite vertex - checking results and the edge - checking results 系統的正向通道為帶有參數不確定性的線性系統,其不確定性為區間攝動模式,反饋通道為由積分二次約束給出的輸入輸出不確定性加以描述。用minkowski泛函給出區間攝動模式下的攝動界的定義,并給出參數空間中混合攝動模式下系統攝動界的估計式。
