Fuzzy Variable Structure Multiple-model Tracking for Airborne Laser Communication System
High precision tracking system for airborne laser communication is usual to adopt multiple models algorithm with a fixed structure,which brings about unnecessary inter-competition among the amount of models and calculation burden.In order to resolve this problem,variable structure multiple-Model based on digraph switching and fuzzy inference was presented,graph switching rule and complete model set were established,the fuzzy inference mechanism was introduced to get matched degree for each filtering,the calculation complexity was decreased obviously.The Kernel particle Filter can move particles toward the posterior,root mean squared error between estimated and true model is minimum,the method could be introduced into fuzzy VSMM framework.Simulation results show that the algorithm improves the accuracy of tracking by reducing the competition of the models as well as reducing the computation burden.
