Abstract: Aiming at the problem that traditional fixed parameter filter lose its precision due to parameter variation of torpedo integrated navigation system model in complicated environment, a multi-model adaptive federated Kalman filter is designed for a torpedo integrated navigation system. The Kalman filter adopts multi-model adaptive federated filtering algorithm, which can approximate the dynamic performance of the system by making use of multi-model filter parameters. Furthermore, an adaptive information distribution strategy for information fusion is employed in the federated filter. The results of navigation test in laboratory show that the multi-model adaptive federated Kalman filter can improve estimation precision, tracking speed and stability of the navigation system greatly. -
