Unmanned gyroplane control system

The utility model relates to an unmanned autorotorcraft control system which comprises a mast and a rotor support, the rotor support is hinged to the top of the mast, the two sides of the mast are each provided with a rotary steering engine, each rotary steering engine is connected with and drives a rotary rod, the end of each rotary rod is hinged to a connecting rod, and the connecting rods are connected with the rotary steering engines. The two connecting rods are hinged to the two sides of the rotor wing support correspondingly. When the rotary steering engines on the two sides rotate in the same direction, the two connecting rods driven by the rotary steering engines pull the rotor wing support to be lifted or pulled down at the same time, and pitching of the rotor wing support is achieved. When the rotary steering engines on the two sides perform differential motion, the two connecting rods driven by the rotary steering engines pull the rotor wing support to incline towards one side, and the rolling acti
