中文摘要
      在网络系统中, 滤波器得到的观测量通过有限带宽的通道进行传送可能发生丢失. 本文研究一类具有测量数据部分丢失的网络化系统的l-l滤波器设计问题. 测量数据的丢失采用已知概率分布的二进制切换序列来描述. 利用线性矩阵不等式方法, 设计全阶和降阶滤波器. 所设计的滤波器使得滤波误差系统均方指数稳定, 而且保证相对于所有有界的外界扰动信号, 滤波误差系统具有一定的l-l扰动衰减水平. 数字仿真表明设计方法的有效性.
英文摘要
      In networked systems, observation data transmitted to the estimator through limited bandwidth channels may be lost. The problem ofl2-l-infinity filter design is addressed for networked systems with missing measurements. The missing measurements are described by a binary switching sequence satisfying a conditional probability distribution. The main purpose is to obtain both full- and reduced-order filters such that the filter error systems are exponentially mean-square stable and guarantee a prescribed energy-to-peak disturbance attenuation level in term of linear matrix inequalities (LMIs).An illustrative numerical example is provided to demonstrate the usefulness and flexibility of the proposed design approach.
