The invention discloses an undercarriage actuator cylinder retracting and releasing control system which comprises a motor, an actuator cylinder with a single piston rod and a hydraulic control system, and the hydraulic control system comprises a first oil way, a second oil way, an oil tank oil way, an oil tank, a hydraulic pump, an oil supplementing one-way valve and a hydraulic control one-way valve; the hydraulic pump is connected with a rodless cavity of the actuator cylinder through a first oil way and further connected with a rod cavity of the actuator cylinder through a second oil way. An oil inlet of the oil supplementing one-way valve is connected with the oil tank through the oil tank oil way, and an oil outlet of the oil supplementing one-way valve is connected to the second oil way. An oil inlet of the hydraulic control one-way valve is connected with an oil tank through an oil tank oil way, an oil outlet of the hydraulic control one-way valve is connected to the first oil way, and a control port of the hydraulic control one-way valve is connected with the second oil way. The hydraulic control system is simple in structure, integration and modular design are facilitated, and the problem that the oil quantity of a rod cavity and the oil quantity of a rodless cavity of a single-piston-rod actuator cylinder are poor is well solved.
