Abstract��
To design the autopilot of the missile controlled by both lateral thrust and aerodynamic force, an approach utilizing the combination of optimal control and the frequency analysis in classic control was proposed. The autopilot structure and the gain values were obtained according to optimal control, and the frequency analysis was used to determine the weighting parameters in objective function, to make sure the robustness of the system. Then the simulation results were compared with the traditional method obtained, it shows that the system response becomes faster and a litter more overshoot appears when using the autopilot bought out, the robustness of the system is also indicated.
