| 摘 要： | 对于带有相关噪声和未知噪声统计的多传感器线性离散定常随机系统,利用相关方法,提出了噪声统计信息的在线估计器.基于ARMA新息模型,提出了自校正加权观测融合Kalman滤波器,避免了求解Lyapunov和Riccati方程,减少了计算负担,适于实时应用.利用动态误差系统分析(DESA)方法,严格证明了提出的自校正融合滤波器以概率1或按实现收敛于相应的最优融合滤波器,即具有渐近全局最优性.一个3传感器系统的仿真例子说明其有效性.

| Abstract: | For the multisensor systems with correlated noises and unknown noise statistics,by correlation method,the online estimators of the noise statistics are obtained.Based on ARMA innovation model,a self-tuning weighted measurement fusion Kalman filter is presented,which avoids Lyapunov and Riccati equations,reduces the computational burden and is suitable for real time application.By dynamic error system analysis(DESA) method,it is strictly proved that the proposed self-tuning fused Kalman filter converges to t... |
