This paper addresses the robust finite frequency (FF) distributed filtering problem for uncertain networked control system (NCS) that consists of heterogeneous subsystems. By using past output measurements and considering the frequency information of disturbance signals, the designed distributed memory filter is able to guarantee that the filtering error system is well-posed, stable and has the FF performance. Based on the extended finite frequency bounded realness lemma for uncertain NCSs, the existence condition of robust FF distributed memory filter is derived. Moreover, it is shown that by taking advantage of more past output measurements of NCS, the proposed design procedure can derive a distributed filter that achieves a lower performance bound. Finally, a practical example is given to show the effectiveness of the proposed filter design method.

具有多面体不确定性的网络控制系统的鲁棒有限频率H∞分布式记忆滤波器设计

本文解决了由异构子系统组成的不确定网络控制系统 (NCS) 的鲁棒有限频率 (FF) 分布式滤波问题。利用以往的输出测量值，并考虑干扰信号的频率信息，设计的分布式存储滤波器能够保证滤波误差系统适定、稳定并具有FF性能。基于不确定NCS的扩展有限频率有界真实性引理，推导了鲁棒FF分布式记忆滤波器的存在条件。此外，结果表明，通过利用 NCS 过去更多的输出测量，所提出的设计过程可以推导出一个分布式滤波器，该滤波器实现了更低的性能约束。最后，给出了一个实际例子来证明所提出的滤波器设计方法的有效性。
