Abstract:

A realistic three dimensional pursuit evasion game between a missile and an aircraft is considered by the fuzzy method, which not only reduces the nonlinear model into a linear one, but also deals with the changes of the evader′s motion. Next, the study is conducted by employing the receding horizon control strategy and adjoint technique. An efficient and robust guidance law is derived, while the evader uses maneuvering strategy to avoid capture. Numerical simulation demonstrates that the missile guided by this law can intercept the randomly maneuvering evader precisely.
