| 摘 要： | 针对鲁棒滤波法计算量大和递推过程复杂的不足,通过等价推导,在线改变γf的值,设计了分散优化鲁棒滤波法,使得鲁棒滤波算法递推简单,避免了直接计算滤波增益阵,并减小了主滤波器计算负荷。将该算法应用于GPS/INS系统,仿真结果表明：该方法能在维持系统鲁棒性的同时又提高滤波精度,具有一定的工程实用价值。 |

| Abstract: | In order to solve the disadvantage of robust filter algorithm which has great calculation and complicated deduce processing, an improved decentralized robust filter algorithm was designed through equipollent deduction and the on-line alterable value of Ys- This new algorithm can make deduction simple and avoid calculating filter gain, and it means less calculation for main filter. This algorithm is used to the GPS/INS system and the results of computer simulation show it is very useful for both improving the filter accuracy and enhancing the robustness of system, and it bears engineering practical value. |
| Keywords: | robust filter integrated navigation system state estimation filter gain |
