Abstract :
This paper considers fusion filtering problems of the multi-sensor data fusion system with state time-delays, in which process and measurement noise have unknown statistic characteristic but bounded power. Applying H∞ theory, an optimal fusion filter is presented based on LMI method for discrete-time fusion system. Finally, the theory developed is demonstrated by an example of multi-sensor fusion problem.
