The invention relates to the field of undercarriage retracting and releasing system design in the aviation field, in particular to an undercarriage redundancy emergency retracting and releasing system and a control method thereof, which comprise a plurality of groups of hydraulic actuating cylinders and pure electric actuating cylinders which are arranged in parallel, and a power source and a control method of the hydraulic actuating cylinders and the pure electric actuating cylinders. Wherein the uplock hydraulic actuating cylinder and the uplock pure electric actuating cylinder jointly act on the uplock supporting rod, the downlock hydraulic actuating cylinder and the downlock pure electric actuating cylinder jointly act on the downlock supporting rod, and the retractable hydraulic actuating cylinder and the retractable pure electric actuating cylinder jointly act on an aircraft landing gear. The hydraulic power source unit and the hydraulic energy accumulator serve as a main power source and a standby power source of the hydraulic actuator cylinder, and the solar cell serves as a power source of the pure electric actuator cylinder. The main controller and the standby controller jointly control system operation through the data analysis and processing module. When the aircraft landing gear folding and unfolding system breaks down, redundancy emergency control over the landing gear folding and unfolding system is achieved, and the safety performance of the landing gear folding and unfolding system is improved.
