Compound Robust Control System Design for Direct Thrust and Aerodynamic Force Missile

Mathematical model based on the small perturbation of air defense missile in the atmosphere is adopted.Double channel compound control scheme is applied to decouple the channel coupling.The linear quadratic optimal regulator is used in the internal closed loop to control the perturbation errors in certain extent.External loop employ mixed sensitivity robust control of multiplication uncertainty model to improve robust performance.By combining with homing guidance mode,a control strategy about the direct force segment is proposed.The result of simulation calculation shows the decoupling ability and robust performance of the compound controller,and it can effectively reduce the dynamic error and the stable tracking time.
