The invention discloses an aircraft actuating system based on a dual-redundancy electro-hydraulic actuator, and relates to the technical field of electro-hydraulic control. A left wing actuation system and a right wing actuation system of the system respectively comprise an aileron actuation subsystem, a leading edge flap actuation subsystem, a trailing edge flap actuation subsystem, a spoiler actuation subsystem and a hydraulic driving system. The empennage actuating system comprises an elevator actuating subsystem, a rudder actuating subsystem and a hydraulic driving system; each subsystem comprises a dual-redundancy electro-hydraulic actuator, a control system and a control system, the dual-redundancy electro-hydraulic actuator comprises a four-cavity hydraulic cylinder, an open valve control unit, a closed pump control unit and a displacement sensor; the highly-integrated four-cavity hydraulic cylinder is adopted as an actuator of the aircraft actuation system, the closed pump control unit and the open valve control unit are combined to form a heterogeneous redundant actuation system, the weight and the size of the aircraft actuation system can be reduced, and the reliability is improved.
