【摘要】 针对H∞鲁棒滤波实现算法在SINS/GPS组合导航系统中的适应性问题,将中央H∞滤波和次优后置H∞滤波用于开环SINS/GPS组合系统和闭环SINS/GPS组合系统中,进行滤波校正,结果表明:中央H∞滤波适于用在开环SINS/GPS组合系统中,次优后置H∞滤波适于用在闭环SINS/GPS组合系统。该结论可对组合导航系统中滤波算法的选取提供参考。更多还原

【Abstract】 In view of the applicability of H∞ robust filtering algorithms to the designed SINS/GPS integrated navigation system,both of the H∞ center filter and the H∞ posteriori filter are applied to an open-loop SINS/GPS integrated system and an closed-loop SINS/GPS integrated system respectively.The simulation results show that the H∞ center filter is applicable to the open-loop SINS/GPS integrated system,while the H∞ posteriori filter is applicable to the closed-loop SINS/GPS integrated system.This conclusion can be a reference for selecting right filtering algorithms in SINS/GPS integrated navigation system.更多还原
