Abstract: In order to effectively adjust attitude motion of interceptor missile by combine control, an attitude control method was presented. A mathematical model of interceptor missile was constituted based on moment of momentum theorem. And with a view to mathematical model and fire logic of thrusters, a neural network controller of attitude motion system was designed for interceptor missile: acquiring basal controller based on simple method, and adjusting control parameters of simple controller using neural network. A desired pitch control moment and yaw control moment were obtained using optimal principle for interceptor missile. Simulation results show that this attitude control method can implement efficiently precise attitude control of interceptor missile as well as preferable dynamic performance.
