摘要
阐述了H∞ 滤波器的设计方法 ,建立了惯导系统初始对准的误差模型 ,并用状态解耦方法对模型进行了可观性分析。最后应用H∞ 滤波方法对可观的子系统进行了滤波器设计 ,给出了设计结果及相应的仿真曲线 ,仿真结果表明H∞滤波在惯导系统中应用是有效的。
This paper presents the method of H\-∞ filter. The error model of inertial navigation system has been derived. State equation decomposition method is applied for analyzing observability of the system. In the end, the H\-∞ filter is designed to the observable small system. The simulation results are gived. The results illustrate robust H\-∞ filtering may be applied in inertial navigation system.
