【摘要】：為解決一類受信道衰落影響的隨機時變時滯系統(tǒng)的故障估計問題,利用一系列相互獨立且服從伯努力分布的隨機變量描述通訊時滯的隨機發(fā)生特性。通過改進的L階萊斯衰落模型反映信道衰落現(xiàn)象,應(yīng)用Lyapunov穩(wěn)定性理論、隨機分析技術(shù)和LMI(Linear Matrix Inequality)技術(shù)得到故障估計器存在的充分條件,在求解LMI的可行解后,給出期望估計器增益的表達式。通過數(shù)值仿真得到了確保增廣的故障估計動態(tài)系統(tǒng)均方指數(shù)穩(wěn)定且滿足H∞性能約束的估計器增益,從而證明了該故障估計方法的有效性。
[Abstract]:In order to solve the problem of fault estimation for a class of stochastic time-varying time-delay systems affected by channel fading, a series of independent random variables with slave effort distribution are used to describe the stochastic occurrence characteristics of communication delays. The improved L order Rice fading model is used to reflect the channel fading phenomenon. By using Lyapunov stability theory, stochastic analysis technique and LMI (Linear Matrix inequality) technique, sufficient conditions for the existence of the fault estimator are obtained. The expression of the desired estimator gain is given. By numerical simulation, the estimator gain is obtained to ensure the mean square exponent stability of the augmented fault estimation system and satisfy the H 鈭，
