The invention discloses a flight control system and method for ship-borne unmanned aerial vehicle autonomous landing. The method comprises the steps that the precise height of an unmanned aerial vehicle can be obtained through data fusion of a laser height sensor and an atmospheric pressure altimeter, the relative positions of the unmanned aerial vehicle and a ship-borne platform can be obtained through a differential GPS, the ship-borne flight control system can work out the size of a flapped foil, the size of an elevator, the size of an accelerator and the size of a rudder according to the information and the expected flight path of the unmanned aerial vehicle, and the unmanned aerial vehicle is controlled to land according to the preset track. According to the control scheme, the height of the unmanned aerial vehicle can be obtained through data fusion of the laser height sensor and the atmospheric pressure altimeter; compared with a traditional atmospheric pressure altimeter, the height is measured more rapidly and more accurately; compared with a traditional single-input and single-output controller, a total energy control system with pitch angle negative feedback is adopted for the flight control law, and the height and the speed are more precisely controlled; compared with a total energy control system with no pitch angle negative feedback, the flight control system has the advantages that the glide and landing attitudes of the unmanned aerial vehicle can be controlled, and the flight safety of the unmanned aerial vehicle is ensured.
