摘要
针对组合导航定位精度和稳定性的要求,将简化的Sage-Husa自适应算法与衰减因子自适应滤波算法相结合,提出了一种改进的Sage-Husa算法,并将该算法应用到组合导航系统中。仿真结果表明,和简化的Sage-Husa算法相比,改进的自适应算法能够同时保证信息融合的精度和稳定性,滤波性能得到了改善。
In order to meet the requirement of precision and stability, a new method which combines the simplified Sage-Husa adaptive algorithm and adaptive fading algorithm is proposed. We apply this method into GPS/SINS intergrated system. Compared with the simplified Sage-Husa adaptive filter,the simulation result shows the new algorithm guarantees the precison and stability of data fusion and the filter peromance is improved.
