分布式多传感器系统的一个关键问题是如何在融合中心将各分站的局部估计进行最优融合.分布式Kalman滤波因其具有分布式估计的诸多优点,并能达到中心式估计的最优性能而受到广泛关注.针对分布式不确定动态系统的H_8滤波给出了最优融合公式,并证明其同样能够达到中心式的融合性能,通过仿真实例验证了该最优融合的有效性.
分佈式多傳感器繫統的一箇關鍵問題是如何在融閤中心將各分站的跼部估計進行最優融閤.分佈式Kalman濾波因其具有分佈式估計的諸多優點,併能達到中心式估計的最優性能而受到廣汎關註.針對分佈式不確定動態繫統的H_8濾波給齣瞭最優融閤公式,併證明其同樣能夠達到中心式的融閤性能,通過倣真實例驗證瞭該最優融閤的有效性.

For distributed multi-sensor system, it is critical to optimally fuse the local estimates in the central processor. Distributed Kalman filtering attracts wide attention because it has many advantages of distributed estimation and can reach the performance of central estimation. The optimal fusion formulation for H_8 filtering in distributed uncertain system is presented, and the performance of the distributed estimation fusion can attain the optimality as same as that of the central estimation is proved. The simulation example shows the effectiveness of the optimal fusion.
