| Abstract: | In this paper, the optimal information fusion for sampled linear systems was studied where the sensors were dis.tributed and measurements were collected to central unit via a wireless network. Every sensor measurement was subject torandom delay or might even be completely lost. The optimal sensor fusion was designed as a time-varying Kalman filterwith bufferized measurements. Finally, the simulation results show the validity of the Fusion estimator. |
