【摘要】 对于带有未知模型参数和未知相关噪声统计的多传感器随机系统,基于ARMA新息模型,利用相关方法,用平均局部的模型参数和噪声统计估值器的方法,提出了模型参数和噪声统计信息的在线信息融合估计器,它们可以被解释为最小二乘融合估计,并证明了相应的辨识器具有强一致性,即以概率1收敛于相应的真实值。一个2传感器系统的仿真例子说明其有效性。更多还原

【Abstract】 For the multisensor stochastic systems with unknown model parameters and unknown noise statistics,based on ARMA innovation model,by correlation method,using the method which makes the average of the local estimators of the model parameters and noise statistics,the online information fusion estimators of model parameters and noise statistics are presented.Which can be viewed as the least squares fused estimation,and the strong consistence of the corresponding identifiers is proved.That is,those identifiers converges to corresponding true values with probability one.A simulation example for a 2-sensor system shows its effectiveness.更多还原
