Optimal and self‐tuning weighted measurement fusion Kalman filters and their asymptotic global optimality

Abstract: For the multisensor linear discrete time-invariant stochastic systems with unknown noise variances, using the correlation method, the information fusion noise variance estimators with consistency are given by taking the average of the local noise variance estimators. Substituting them into two optimal weighted measurement fusion steady-state Kalman filters, two new self-tuning weighted measurement fusion Kalman filters with a self-tuning Riccati equation are presented. By the dynamic variance error system anal… Show more

“…Self-tuning decoupled fusion Kalman predictor is proposed in [160] and self-tuning weighted measurement Kalman filter is included in [161]. Self-tuning measurement system using the correlation method, can be viewed as the least-squares (LS) fused estimator and found in [285]. Self-tuning distributed (weighed) measurement fusion Kalman filters is shown in [292,293,294].…”

“…Applying the dynamic error system analysis (DESA) method [9], it can rigorously proved that the self-tuning WMF filter converges to the steady-state optimal WMF filter in a realization, so it has asymptotic global optimality [3].…”

“…The autoregressive moving average (ARMA) signal model can be transformed to the state space model, so the information fusion estimation problem of the ARMA signal can be solved by estimating the state due to the signal can be considered as the partial components of the state [2]. The weighted measurement fusion(WMF) Kalman filtering method [3] is an important distributed fusion method, which has the global optimality. However, when the measurements to the ARMA signal have sensor bias and common disturbance noise, the computational burden of the fused measurement and the fused measurement noise variance is large.…”
