Adaptive Fuzzy α-β-γ Filter and Its Application

α-β-γ filter is widely used in target tracking.But for tracking maneuvering targets,it cannot satisfy the re- quirements on filter convergence and accuracy.Multi-level combined α-β-γ filter can improve the tracking accuracy,but it also brings the problem of computational complexity especially when tracking multi-targets.This paper presents the adaptive fuzzy α-β-γ filter,the problem among filter accuracy,.convergence and computational complexity can be solved by fuzzy adjusting parameters according to filter error.Simulation shows that adaptive fuzzy α-β-γ filter can satisfy the convergence of maneuvering target,but also can improve tracking accuracy.
