Precision Distribution Method of Navigation System Based on Improved Artificial Fish Swarm Algorithm

In order to solve the problem of navigation system precision distribution, an adaptive fast precision distribution method is proposed in detail, which is based on the improved artificial fish swarm algorithm It combines the concepts of Genetic Algorithm and Simulated Annealing, adaptively adjusting the control parameters, and restructuring the standard tracking relationship of artificial fish swarm algorithm, so the proposed algorithm can avoid local optimum and improve calculating precision, speed and expansibility. The improved algorithm is applied to distribute the subsystem precision of navigation system with Monte-Carlo method. The simulation results illustrate the improvement of searching precision and speed, the ability to avoid local optimum, and the effectiveness of distribution calculation on navigation system.
