用随机马尔可夫跳变系统描述一类具有丢包时延的网络控制系统.为这类网络控制系统设计马尔可夫跳变滤波器,保证了滤波误差系统均方意义下随机渐近稳定,且噪声信号对估计误差的影响低于指定H∞性能水平,滤波器参数可通过求解线性矩阵不等式得到.最后通过仿真实例验证了所得结论的正确性和滤波器设计方法的有效性.
A kind of networked control system with packet loss delay is described by using stochastic Markov transition system.The Markov hopping filter is designed for such a networked control system to ensure that the filtering error is stochastically asymptotically stable in the sense of the mean square, And the effect of noise signal on the estimation error is lower than the specified H∞ performance level, the filter parameters can be obtained by solving the linear matrix inequality. Finally, the simulation results verify the validity of the conclusions and the effectiveness of the filter design method.
