摘要
为更好评估滤波算法的稳定性,在分析影响滤波算法稳定性因素的基础上,提出滤波算法稳定性评估指标,建立了其数学模型,构建了滤波算法稳定性评估指标体系,以卡尔曼滤波在INS/GPS初始对准中的应用为例,依据该指标体系对卡尔曼滤波的稳定性进行了评估。仿真结果表明,稳定性评估结果与理论分析一致。
To better evaluate the stability of filtering algorithm,based on the analysis of the factors affecting factors,the stability evaluation index filtering algorithm is proposed,with its mathematical model established,and the stability evaluation index system is constructed.Taking the application of kalman filtering used in initial alignment in integrate INS/GPS navigation system as an example,stability of kalman filtering is evaluated according to the index system.Simulation results show that the stability evaluation results are in consistent with theoretical analysis.
