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 L2L 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-disturbance fault-tolerant controller is proposed for switched systems with multiple disturbances and actuator faults. The disturbances are divided into two parts: One is assumed to be a norm-bounded vector; the other part is generated by an exogenous system with parametric perturbations. First, a composite observer is constructed to estimate the disturbances described by an exogenous system and actuator fault simultaneously. Then, based on disturbance observer based control (DOBC), fault accommodation, and L2L control, a composite anti-disturbance fault-tolerant controller is developed to reconfigure the considered systems with disturbance rejection and attenuation performance. By virtue of average dwell time method and Lyapunov function technique, the stability of the closed-loop system is analyzed. Finally, a numerical example is presented to demonstrate the effectiveness of the proposed control approach.
