The invention provides a helicopter tail cabin door folding and unfolding dual-redundancy control system, and the system comprises a first control system which is connected with a helicopter tail cabin door; the second control system is connected with the helicopter tail cabin door; when the first control system fails, the second control system automatically works, and the tail cabin door is retracted and released; during heavy-load expansion, the first control system and the second control system work at the same time, and the tail cabin door is retracted and released in a heavy-load scene; meanwhile, the invention further provides a helicopter tail cabin door folding and unfolding dual-redundancy control method. When one set of control system fails, the other set of control system is automatically started to carry out tail cabin door retracting and releasing control, and the task reliability of tail cabin door retracting and releasing is effectively improved.
