The invention relates to the field of rehabilitative prosthetics and orthotics, in particular to a dynamic hip joint prosthesis control system. The dynamic hip joint prosthesis control system comprises a gait information collection module, a gait information processing module, a control module, a motor driving module, a communication module, a motor power supply module, a control power supply module, a photo coupler isolation module and a Kalman filtering module; and the control system receives plantar pressure information and knee joint and hip joint flexion and extension information, collected by the gait information collection module, through the communication module, the received information is processed to generate a control signal, and the motor driving device (module) receives the control signal through the communication module to drive a dynamic hip joint prosthesis to run, so as to drive a patient to walk. The provided dynamic hip joint prosthesis control system has the advantage that strength needed by the patient to walk is reduced so that the patient can walk conveniently.
