Guidance and control system design of submarine-to-air missile based on optimal control

A new design method of guidance and control system for the submarine-to-air missile based on optimal theory is presented in this paper. Firstly, the small perturbation linearized state space models of pitch channel for both torpedo underwater mechanics and missile flight mechanics are established. Then the guidance and control system is designed by linear quadratic (LQ) soft terminal controller and optimal guidance law. Finally, it is proved by simulation that the linearized model and the optimal design method are efficient in submarine-to-air missile controlling.
