摘　　要：本文针对SINS/GPS组合导航系统中卡尔曼滤波发散的情况:介绍并分析了自适应滤波和H∞滤波算法原理,并进行仿真计算,验证了这两种滤波用于SINS/GPS组合导航系统的可行性和有效性,对实际应用中组合导航系统滤波器的设计具有一定的指导意义。Aiming at the divergence of general Kalman filter in SINS/GPS integrated navigation system, adaptive Kalman filter and H∞ filter were introduced and analyzed. And the simulation was done. The results prove that these two kinds of filter are valid and reliable when applied in SINS/GPS integrated navigation system. Thus, it is significant in practice for filter design in integrated navigation system.
