An Optimal Control Method for Reentry Maneuvering Warhead

In order to gratify the need of terminal guidance, warhead must be capable of achieving definite terminal guidance original work altitude in the design of reentry maneuvering trajectory when the velocity and range of warhead is controlled. Aiming at the above problem, system optimization and control theory were adopted to design reentry maneuvering trajectory and distribute attack angle, moreover, suitably disposing actual calculation process to satisfy the request of engineering design in optimization. Trajectory simulation results showed that the proposed optimization design method in this paper was able to effectively meet reentry maneuver require, and the terminal result deviation was small. It could provide theory condition for engineering application.
