摘要 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. The stochastic Markov jump system is established to describe a class of networked control systems（NCSs）with time-delay and data packet dropout.A Markov jump filter is designed to ensure asymptotic mean-square stability of the filtering error system,which guarantees a prescribed gain level from the noise signals to the estimation error.The desired filter can be constructed by solving a set of linear matrix inequalities.A simulation example shows the effectiveness of the proposed approach.
