发布时间：2018-12-16 02:49
【摘要】：针对带有多干扰和执行器故障切换系统,文章提出了一种复合抗干扰容错控制器.干扰分为两大类:一类假定为范数有界干扰;另一类可看作带有参数摄动的外部系统描述的干扰.首先,设计了复合观测器同时估计由外部系统描述的外部干扰和执行器故障.其次,基于干扰观测器控制方法,故障调节以及L_2-L_∞控制,给出了具有干扰抑制和干扰衰减性能的复合抗干扰容错控制器.借助于平均驻留时间方法和Lyapunov函数方法,分析了闭环系统的稳定性.最后,通过数值例子证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，
