The invention provides a dual-redundancy control system for a main landing gear of an unmanned aerial vehicle, and belongs to the technical field of aircrafts, and the dual-redundancy control system specifically comprises a dual-redundancy controller, an electric mechanism and a limiting mechanism which are arranged on an actuator cylinder of the main landing gear, the dual-redundancy controller is connected with the actuator cylinder of the main landing gear through a controller electric connector, and the electric mechanism is connected with the limiting mechanism. The electric mechanism comprises a first driving motor and a second driving motor, the limiting mechanisms are arranged in the main undercarriage actuating cylinder, the first driving motor and the second driving motor correspond to the corresponding limiting mechanisms respectively, and each limiting mechanism comprises a limit switch and a potentiometer assembly. The dual-redundancy controller receives signals of the limit switch and the potentiometer assembly and controls the electric mechanism. Through the processing scheme provided by the invention, the task reliability and the control precision of the system are improved, and the fault isolation capability of the system is improved.
