摘要
研究了一类线性连续系统网络化H∞滤波问题。提出了一种基于事件驱动的网络传输机制,可以有效地降低数据的网络传输负担。采用输入-时滞技术,构建了增广的滤波误差时滞系统。针对增广的滤波误差时滞系统,采用Lyapunov-Krasovskii泛函方法,以线性矩阵不等式(LMI)的形式给出了其稳定性及H∞性能指标存在充分条件,而后给出了H∞滤波器设计方法。仿真算例有效地验证了基于事件驱动的网络化H∞滤波器的有效性和优越性。
This paper investigates the network H∞ filter new event-driven scheme was developed to conduct the network ,which effectively reduced the transmission load. design for a class of linear continuous-time systems. A data transmission between the system and the filter via With the input-delay approach, we firstly formulated an extended filtering error system. With Lyapunov-Krasovskii functional approach, we presented the stability and existence condition of H∞ performance index for the filtering error system in the form of linear matrix inequality （LMI）. Then a filter design was given. Finally, an example with mechanical system was given to illustrate the ef- fectiveness and the advantages of the event-driven network filter.
