Abstract
For the multisensor systems with unknown model parameters and noise variances, using the system identification method, the online fusion estimators of the model parameters and the noise variances can be obtained, and then substituting them into a centralized fusion optimal information filter, a self-tuning centralized fusion information filter is presented. Compared with the centralized fusion optimal Kalman filter based on the Riccati equation, it can reduce the computational burden. Using the dynamic error system analysis (DESA) method, it is proven that the self-tuning centralized fusion information filter converges with the centralized fusion optimal information filter, so that it has asymptotic global optimality . A simulation example applied to the signal processing shows its effectiveness.
