1. 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(tǒng)的正向通道為帶有參數(shù)不確定性的線性系統(tǒng)，其不確定性為區(qū)間攝動(dòng)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(qū)間攝動(dòng)模式下的攝動(dòng)界的定義，并給出參數(shù)空間中混合攝動(dòng)模式下系統(tǒng)攝動(dòng)界的估計(jì)式。
