【摘要】：當切換系統(tǒng)發(fā)生故障時,通常需要依次進行故障診斷和容錯控制.為了提高切換系統(tǒng)故障診斷的可靠性和容錯控制的及時性,本文提出一種同時故障估計與容錯控制方法.針對滿足平均駐留時間約束的線性切換系統(tǒng),首先建立了基于狀態(tài)觀測器的同時故障估計與容錯控制器,并將其設(shè)計問題轉(zhuǎn)化為了加權(quán)H∞性能指標下增廣誤差系統(tǒng)的多目標求解問題.然后使用平均駐留時間技術(shù)和多Lyapunov函數(shù)方法設(shè)計了故障估計與容錯控制器的參數(shù),又通過松弛矩陣方法進一步得到了保守性較低的結(jié)果.最后,利用一個例子對本文所提方法進行了仿真,證實了該方法的有效性.
[Abstract]:When a switching system fails, fault diagnosis and fault-tolerant control are usually needed in turn. In order to improve the reliability of fault diagnosis and the timeliness of fault-tolerant control in switching systems, a method of simultaneous fault estimation and fault-tolerant control is proposed in this paper. For linear switched systems with average dwell time constraints, a simultaneous fault estimation and fault tolerant controller based on state observer is established. The design problem is transformed into the multi-objective problem of the augmented error system under the weighted H 鈭，
