模糊信息融合方法在分布式基准系统中的应用

由于舰船导航和武器系统的精度和可靠性等要求的不断提高以及分布式指控系统的发展，建立全舰统一姿态基准系统已成为必然。提出了利用测量结果推算出的甲板挠曲姿态信息作为分布式捷联姿态基准系统（简称分布式捷联基准）的补偿信息，然后利用基于模糊理论的信息融合方法建立全舰统一姿态基准系统。最后通过对简易模型的仿真研究，证明了这种方法是可行的并具有较高的精度。

Application of Information Fusion Method Based on Fuzzy Theory in Distributed Strapdown Reference System

Because of the high requirement of the attitude determination of marine navigation and weapon system under the adverse circumstances, and the development of distributed command system, it is necessary to build an unite attitude reference system of the whole ship. The independent strapdown attitude reference systems can not satisfy these requirements. Then, the distributed strapdown attitude reference system (DSARS) composed of several strapdown references on the deck of ship may use the deck deflection attitude information computed from the measurement results as compensation. The information fusion method based on fuzzy theory is used to build an unite attitude reference system of the whole ship is presented in this paper. In the end, the experiment on a simple modal shows that this method is effective and has higher precision.
