The invention provides a closed-loop control system and method for a hydraulic steering system, the hydraulic steering system comprises a steering wheel, a hydraulic steering mechanism and wheels, the steering wheel is connected with the hydraulic steering mechanism through a steering knuckle, and the hydraulic steering mechanism is connected with the wheels through steering wheel shafts of the wheels. The hydraulic steering system closed-loop control system comprises a control device, an ECU, an encoder and a steering servo motor, the ECU is connected with the control device, the encoder and the steering servo motor, the encoder is installed on a steering wheel shaft of an original vehicle wheel, and the steering servo motor is installed on a rotating shaft of an original vehicle steering wheel. According to the closed-loop control system and method for the hydraulic steering system, the wheel steering angle of the hydraulic steering system is accurate, the response speed is high, a mode of directly controlling a hydraulic valve is bypassed, a steering motor is adopted for carrying out accurate steering angle control, and the wheels reach the ideal steering angle through real-time closed-loop control.
