| 摘 要： | 针对有限通信情形下航天器自主交会的故障检测问题，提出了基于Delta算子的鲁棒故障检测滤波器设计方法.采用C-W方程来描述航天器间的相对运动模型，通过Delta算子方法对其进行离散化处理得到系统的离散模型.在故障检测滤波器设计中，考虑信号量化和数据丢包同时存在的情况，并且采用随机伯努利序列来描述数据丢包现象.最后，基于LMI方法给出故障诊断存在的充分条件，并通过数值仿真验证了所设计滤波器的有效性.

| Abstract: | This paper addresses the robust fault detection problem for spacecraft autonomous rendezvous with digital communication constraints.The Clohessy-Wiltshire equation is employed to describe the relative dynamic model,and the discrete-time model with sampling behavior is proposed by using delta operator approach.In this design,the data are exchanged among components of spacecraft,and signal quantization and data packet losses are considered in a unified framework.The stochastic variables with Bernoulli random binary distribution are utilized to describe the random rate dropout.A sufficient condition for the existence of the designed fault detection filter is presented with linear matrix inequalities techniques.Finally,a practical example is illustrated to demonstrate the effectiveness of the proposed fault detection techniques. |
