摘要 研究了范数有界不确定描述模型和多胞形不确定描述模型所代表的一类参数不确定多传感器系统的集中融合估计问题。应用H∞理论详细地比较了基于不同模型的两种融合方法时域和频域功能,给出了集中鲁棒融合估计的理论结果。并应用MATLAB的LMI工具箱,分析了仿真计算结果。 This paper studies two kinds Of uncertain models of uncertainty multisensor system, i.e., norm-bounded uncertainty model and polytopic uncertainty models, and corresponding centralized robust fusion estimation problem. By applying H∞ theory the centralized robust fusion estimation methods is developed. Two fusion methods are compared detailedly in frequency and time domains. Simulation results are analyzed by LMI toolbox of MATLAB.
