Attitude Control System for Laser Terminal Guided Maneuver Warhead

The necessity and feasibility for the application of laser-terminal-guidance technique in maneuver warhead is briefly presented.In view of the particularity for maneuver warhead reentry trajectory and the guidance method,key techniques in attitude control system design are analyzed.Comparing with the traditional control scheme,an integrated control approach based on the instruction feed-forward control plus variable structure feedback control technique is put forward.Simulation result indicates that this scheme has relatively high robustness and satisfies the design requirement.
