The autopilot design issue of a side-jet and aero-fin blending control air-to-air missile is discussed in this paper and a MRVSS (short for "Model Reference Variable Sliding Structure") control method is presented. The MRVSS controller generates control commands to aero-fin actuators and side-jet actuators to make the missile system to reach the desired normal load command. The control law is in the form of full-state feedback and the sliding-surface reachability condition is satisfied. GA (short for "Generic Algorithm") optimization is applied to search the optimal values of control parameters. Simulation results prove that the MRVSS controller has a good performance in tracking the desired command and it ensure the missile control system's fast time response and smooth dynamical process. Moreover, the MRVSS controller is robust to external disturbance and internal uncertainty which is meaningful in the actual industrial applications.
