摘　　要：基于Krein空间状态模型,深入分析H-infinity滤波增益,提出了广义滤波增益、增益失调因子等相关概念,并给出了H-infinity滤波器鲁棒性机理及H-infinity滤波器发散原因等相关结论。在此基础上,建立了一套结构化算法,清晰地描述了H-infinity滤波的两个计算回路和两个更新过程。仿真结果证明了相关结论的正确性。Based on a Krein space state-space model, the H-infinity filter gain was deeply analyzed. Some concepts, such as generalized filtering gain and gain maladjustment gene, etc, were founded, and based on which, H-infinity filter robustness mechanism and H-infinity filter divergence reason and so on were proposed. A suit of structuring algorithm was established, which clearly described the H-infinity filte（s two computing loops and two updating loops. Simulation shows the correlate conclusions are correct.
