基于LMI的Delta域内的H_∞滤波器问题

H_∞Filter LMI-Based in Delta Domain

用LMI方法来研究Delta算子描述下的线性定常系统的H_∞滤波器问题,基于一个LMI给出了Delta域内的H_∞观测器型状态估计器,充分显示了在Delta域内用LMI方法设计的优越性;比较好地给出了随机滤波问题的解决办法,并用一个例子说明了本方法的有效性。

H∞ filter problem of the linear time system in Delta domain is researched using LMI methord, H∞ state estimator based on observer has been presented, it is obviously proved that LMI methord in Delta domain is valid, and this way is better than others in H∞ filter degsin. At last, this methord is shown by an example to be effectiveness.
