【摘要】：針對帶有多干擾和執(zhí)行器故障切換系統(tǒng),文章提出了一種復(fù)合抗干擾容錯控制器.干擾分為兩大類:一類假定為范數(shù)有界干擾;另一類可看作帶有參數(shù)攝動的外部系統(tǒng)描述的干擾.首先,設(shè)計(jì)了復(fù)合觀測器同時(shí)估計(jì)由外部系統(tǒng)描述的外部干擾和執(zhí)行器故障.其次,基于干擾觀測器控制方法,故障調(diào)節(jié)以及L_2-L_∞控制,給出了具有干擾抑制和干擾衰減性能的復(fù)合抗干擾容錯控制器.借助于平均駐留時(shí)間方法和Lyapunov函數(shù)方法,分析了閉環(huán)系統(tǒng)的穩(wěn)定性.最后,通過數(shù)值例子證明了所提方法的有效性.
[Abstract]:In this paper, a composite anti-jamming and fault-tolerant controller is proposed for multi-interference and actuator fault switching systems. There are two kinds of disturbances: one is assumed to be norm-bounded and the other is the disturbance described by an external system with parameter perturbation. First, a composite observer is designed to simultaneously estimate the external disturbances and actuator faults described by the external system. Secondly, based on the disturbance observer control method, fault regulation and L2-L鈭，
