Research on the missile formation keeping optimal control for cooperative engagement

Aimed at the needs of missile cooperative engagement mission, designed the optimal control to keep missile formation. Analyse the frame of missile formation control system from the view of cooperative engagement system. Based on the missile kinematics in relative coordinate frame, structured the missile relative motion model straight, which made the process of motion between missiles became transparent. Considered the states of leader as perturbation variable, designed the missile formation keeping optimal control based on linear quadric optimal theory. Simulations demonstrate that the formation keeping optimal control is capable of restraining perturbation variable brought by model, leader states and linearizing analyse, and is able to implement the reconfiguring and keeping expected formation rapidly, stably and exactly.
