摘要
研究了一类具有网络诱导时延和随机丢包的连续线性系统网络化H_∞滤波问题.考虑区间有界的网络诱导时延和伯努利分布刻画的丢包现象,将网络化滤波误差系统建模为一类带有重置方程的时滞脉冲系统.构造合适的Lyapunov-Krasovskii泛函并评估脉冲时刻的能量变化,以可求解的线性矩阵不等式形式设计滤波器,使得滤波误差系统均方渐近稳定并满足给定的H_∞干扰抑制水平.通过仿真验证设计方法有效性.
The networked H_∞ filtering problem of a continuous-time linear system is addressed by taking network-induced delay and random packet loss into consideration. Due to the effect of bounded network-induced delays and random packet dropouts characterized by Bernoulli distribution,the networked filtering error system is modeled as a delay impulsive system with reset equations. Using an appropriate Lyapunov-Krasovskii approach and considering the energy change around the impulsive instants,the networked filter is designed in terms of solvable linear matrix inequalities so that the error system is asymptotically mean-square stable with prescribed H∞performance.A simulation example illustrates the effectiveness of the proposed method.
