摘要: 针对一类后掠翼可变的变体飞行器,考虑同时存在状态时滞和随机丢包的网络环境,基于切换系统理论,研究了变体飞行器闭环故障检测滤波器的设计问题。将变体飞行器建模成以高度、马赫数和后掠角为参变量的切换系统。为了保证系统能够有效检测出系统故障并且跟踪指令信号,基于一体化方法,设计基于模态依赖观测器的故障检测滤波器和基于残差估计的输出容错控制器。通过多Lyapunov-Krasovskii函数方法和平均驻留时间方法分析系统在异步切换情况下的稳定性。以线性矩阵不等式的形式给出满足给定性能指标滤波器和控制器存在的充分条件。通过仿真验证了所提方法能够有效检测出故障,输出信号能够准确跟踪指令信号,且在不确定情况下具有较好的鲁棒性。

Abstract: Considering the state delay and missing measurements in the network environment, the closed-loop fault detection for the morphing aircrafts with alterable sweep wings is investigated based on the switched system theory. The morphing aircraft is modeled as switched system which takes the altitude, Mach and wing sweep angle as parameters. Based on the integrated design method, the mode-dependent observer-based filter and the state estimation feedback controller are derived to ensure that the fault signal can be detected efficiently and the output can track the command signal accurately. The stability of the system is guaranteed by Lyapunov-Krasovskii functional method and average dwell time method. The sufficient existing conditions of filter and controller are given in the form of linear matrix inequalities (LMI). The simulated results show that the proposed method can detect the fault signal efficiently, the output can be used to track the command signal, and the system is robust to parameter uncertainties.
