【摘要】：當(dāng)切換系統(tǒng)發(fā)生故障時(shí),通常需要依次進(jìn)行故障診斷和容錯(cuò)控制.為了提高切換系統(tǒng)故障診斷的可靠性和容錯(cuò)控制的及時(shí)性,本文提出一種同時(shí)故障估計(jì)與容錯(cuò)控制方法.針對滿足平均駐留時(shí)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(shí)故障估計(jì)與容錯(cuò)控制器,并將其設(shè)計(jì)問題轉(zhuǎn)化為了加權(quán)H∞性能指標(biāo)下增廣誤差系統(tǒng)的多目標(biāo)求解問題.然后使用平均駐留時(shí)間技術(shù)和多Lyapunov函數(shù)方法設(shè)計(jì)了故障估計(jì)與容錯(cuò)控制器的參數(shù),又通過松弛矩陣方法進(jìn)一步得到了保守性較低的結(jié)果.最后,利用一個(gè)例子對本文所提方法進(jìn)行了仿真,證實(shí)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，
