摘要: 鉴于网络控制系统存在随机时延和参数不确定问题,设计了一类 H 滤波器。首先,引入Bernoulli 序列构建多通道随机时延模型,运用变量分解法分离系数矩阵的不确定项。然后,基于增广向量技术描述差异时延的滤波误差系统,运用 Lyapunov 理论定量分析 H 性能指标,并寻得使滤波器存在的充分条件。最后,通过求解一组滤波器参数验证了所提算法的有效性。

Abstract: The design of H filter was studied for random time delays and parameter uncertainty of network control systems. Firstly,the model was given to describe the systems with multi-channel random time delays by the Bernoulli sequence,and the uncertainties of the coefficient matrix were separated by the variable decomposition method. Then,the filtering error systems with different delay rates were constructed by augmented vectors,H performance metrics were quantitatively analyzed by Lyapunov theory, and sufficient conditions for the existence of filters were sought. Finally,the effectiveness of the proposed filter algorithm was verified by solving a set of filter parameters.

Key words: random time delays, parameter uncertainty, filtering, Bernoulli sequence
