Design and Performance Analysis of Robust Fusion Filters for a Class of Continuous Uncertain Dynamic Systems

The design problems of robust fusion filters for uncertain multi-sensor dynamic systems are dealt with by means of combining the traditional robust theory and data fusion technology. In terms of parameter-dependent Lyapunov function, a kind of design methods robust H

fusion filters are discussed. Based on the research for the robustness of the filter and its resolvent, the performance of the robust fusion filters for the multi-sensor dynamic systems is compared by simulation example. Simulation results show that the proposed design method have a better robust performance for the filter problems when parameter uncertainties exist in the system model.
