Robust design method for flight control system of cruise missile

The flight control system design method of wing-in-ground effect aircraft is presented based on robust control theory. With a view to uncertainty of lengthways channels, the simplified mathematical model is constituted for wing-in-ground effect aircraft. According to this simplified model, the lengthways control system is designed. In order to overcome defect of uncertain system, the flight controller of wing-in-ground effect aircraft is designed using robust control theory. Simulation results show that this control method can implement efficiently precision control mission for wing-in-ground effect aircraft as well as preferable robustness.
