中文摘要
      研究了一类带宽受限网络化系统的广义H2滤波问题. 滤波器采用量化后的测量信号作为其输入信号, 采用对数量化器, 将滤波误差系统建模成范数有界不确定时滞系统. 利用Lyapunov 稳定性理论和线性矩阵不等式(LMI)技术, 得到了滤波误差系统渐近稳定的充分条件以及滤波器的设计方法. 数值示例验证了所给算法的可行性.
英文摘要
      The generalized H-two filtering problem is studied for a class of networked systems with bandwidth constraints. The quantized measurement signal is used as the input of the filter. Then, by using the logarithm quantizer, we model the filter-error system as a time-delay system with norm-bounded uncertainty. Sufficient conditions are derived for the asymptotic stability of the filter-error system by the Lyapunov stability theory and the linear matrix inequality (LMI) technique; and the design procedures for the filter are also provided. A numerical example is provided to illustrate the feasibility of the proposed method.
