中文摘要
      本文研究了存在时变短时延和随机丢包的大包线网络化飞行器故障检测问题. 首先, 采用切换多胞系统描述飞行动态, 并提出了一种局部重叠多胞划分方式以较低设计保守性. 然后, 借助泰勒级数展开和伯努利分布将时 延和丢包转化为多胞系统参数, 并构建了切换参数依赖故障检测滤波器. 同时, 考虑滤波器切换指令及多胞加权参数更新滞后引起的异步切换问题, 基于切换参数依赖Lyapunov函数和平均驻留时间方法分析了系统的稳定性和l_2性能, 并以LMI形式给出了滤波器存在的充分条件. 最后, 以HiMAT(highly maneuverable technology)飞行器为例验证了所提方法的有效性.
英文摘要
      The fault detection problem is investigated for the full-envelope networked flight vehicle with time-varying short delay and stochastic packet loss. First, the flight dynamics is modeled as a switched polytopic system, and a locally overlapped region partition method is presented to reduce the design conservatism. Then, the delay and packet loss can be transformed as polytopic system parameters by introducing Bernoulli distributing and Taylor series expansion, and the switched parameter-dependent fault detection filters are established. Also, considering the updating lags of the filter switching signals and weight parameters of the polytopic subsystems, we analyze the system stability and l_2 performance under asynchronous switching by combing the switched parameter-dependent Lyapunov function and the average dwell time method, and the sufficient existing conditions of filters are derived in the form of LMIs. Finally, numerical examples based on the HiMAT (highly maneuverable technology) vehicle are given to demonstrate the effectiveness of the proposed method.
