Decentralized H∞ fusion filter design in multi-sensor fusion system

There are in general two different types of methods to process the measured sensor data for multi-sensor fusion system. The first one is the centralized fusion filter, the other is decentralized fusion filter. Both of them have their own advantages and disadvantages. This paper mainly considers decentralized fusion filtering problems of the multi-sensor fusion system on basis of H_infin filtering theory, the process and measurement noise in the system have unknown statistic characteristic but bounded power. Applying LMI methods, a new approach to design the H_infin filter is presented. Finally, an example is given to illustrate the effectiveness of our theory.
