The invention provides an aircraft slat fatigue test follow-up system. The aircraft slat fatigue test follow-up system comprises a follow-up loading mechanism and an angle tracking control system, the follow-up loading mechanism comprises a frame support, a follow-up frame hinged to the frame support, a driving actuating cylinder used for driving the follow-up frame to rotate and a loading actuating cylinder hinged to the follow-up frame and connected with the airfoil test piece; the angle tracking control system comprises a coordinated loading control system, a force transducer and a tilt angle sensor mounted on the follow-up frame, and the coordinated loading control system receives a displacement signal of the driving actuator cylinder, a force signal of the force transducer, an angle measurement signal of the tilt angle sensor, and a deflection angle signal and an angle difference signal of the slat airfoil driving system; the deflection angle signal is corrected through the angle measurement signal to obtain the relation between the displacement elongation of the driving actuator cylinder and the wing surface deflection angle, and the coordinated loading control system controls the action of the driving actuator cylinder according to the corrected relation between the displacement elongation of the driving actuator cylinder and the wing surface deflection angle.
