Centralized and distributed robust state fusion estimation

The study of robust state estimation for uncertain multisensor system is an important field of multisensor fusion estimation theory.Based on robust filtering theory,this paper develops polytopic models of uncertain multisensor system and centralized robust fusion estimation by linear matrix Inequality(LMI) method,and proves the exact transforming condition,by which robust centralized estimation can be transformed to the distributed fusion method with the same fusion estimation performance.Finally,an example is given to illustrate the estimation approach for the distributed uncertain multisensor system.
