The current model probability of interacting multiple model (IMM) algorithm based on current statistical model is difficultly decided

and the system parameter and can not be adaptive adjusted. So a modified IMM algorithm based on current statistical model is presented via adaptive fuzzy logic for improving the tracking speed. The design parameters of the modified algorithm are optimized with ant algorithm for improving the tracking precision. Finally

to demonstrate the availability of the modified IMM tracking algorithm based on current statistical model

a simulation example is given. The simulation results suggest the modified algorithm is valid.
