Guidance and Control Integrated Design and Simulation of Air-to-Surface Miniature Missile

An Air-to-Surface miniature missile is taken as the investigation object,the problem of integrated guidance and control for homing missiles is investigated. The integrated guidance and control model for the pitch and yaw independent design is established,and it is changed into a common form of subsystem with unknown limitary uncertainties. Adaptive nonlinear integrated guidance and control law was designed by adopting sliding-mode approach. The 6DOF nonlinear air-to-surface missile simulation results demonstrate the feasibility and effectiveness of the proposed integrated guidance and control algorithm. The controller can not only ensure the stability of the missile dynamics,but also achieve the high guidance accuracy.
