摘要
为了防止组合导航局部滤波器性能变化而调整信息分配的问题,本文分析了联合卡尔曼滤波算法中参考系统、主滤波器以及局部滤波器的特点,具体描述了组合导航系统的联合滤波算法,提出了一种基于广义特征值分解的自适应信息分配策略。该结果表明,在工程实践上,采用组合导航信息融合技术可以解决根据组合导航局部滤波器性能随时调整信息分配策略的问题。
In order to prevent the performance of integrated navigation local filter from changing to adjust the distribution of information, the paper analyzed the reference system, main filter and local filter in the federated Kalman filter algorithm, described the federated filter algorithm of the integrated navigation system, put forward a kind of adaptive information distribution tactics resolved based on generalized eigenvalue. The result shows that the technology can resolve the problem that the distribution of information can be adjusted according to the performance of integrated navigation local filter in the project practice.
