INS地面自对准的鲁棒性分析

讨论了惯性导航系统（ＩＮＳ）地面自对的鲁棒性能问题。文中指出当采用两个水平方向加速度计作为测量时，ＩＮＳ的地面自对准稳态性能与设计滤波民采用的噪声方差无关。但由于自对准的时间限制，实际自对准性能鲁棒性，即滤波器的稳态性能，可以通过鲁棒设计得进。利用对策论原理，文中给出了最优鲁棒ＩＮＳ自对准设计方案。

Robustness Analysis of INS Ground Alignment

Discusses the performance robustness of an Inertial Navigation System (INS)ground alignment. It points out that the steady state performance of the INS ground alignrnent is not affected by the choice of the noise covariances in the design of Kalman filters when two level accelerations are used in the measurement. However because of the limitation of the alignment time in reality, the alignment performance robustness of the ground alignment can be enhanced by robust design. The optimal robust INS ground alignment scheme is presented using game theory.
