Abstract EN
The distributed fusion state estimation problem is addressed for sensor network systems with random state transition matrix and random measurement matrices, which provide a unified framework to consider some network-induced random phenomena.
The process noise and all the sensor measurement noises are assumed to be one-step autocorrelated and different sensor noises are one-step cross-correlated; also, the process noise and each sensor measurement noise are two-step cross-correlated.
These correlation assumptions cover many practical situations, where the classical independence hypothesis is not realistic.
Using an innovation methodology, local least-squares linear filtering estimators are recursively obtained at each sensor.
The distributed fusion method is then used to form the optimal matrix-weighted sum of these local filters according to the mean squared error criterion.
A numerical simulation example shows the accuracy of the proposed distributed fusion filtering algorithm and illustrates some of the network-induced stochastic uncertainties that can be dealt with in the current system model, such as sensor gain degradation, missing measurements, and multiplicative noise.
