The invention relates to a magnetic nail based automatic rail-mounted gantry crane cart positioning control system and method. The control system comprises cart rails, a rail crane cart running on thecart rails, a positioning unit and a control unit, wherein the positioning unit and the control unit are mounted on the rail crane cart. The positioning unit comprises a master controller, a variablefrequency driver and an encoder. The control unit comprises cart drivers and driving motors, and the cart drivers and the driving motors are mounted on the rail crane cart and connected mutually. Thepositioning unit further comprises a magnetic nail assembly connected with the master controller and used for transmitting the reference position. The control unit further comprises a PID controllerconnected with the master controller, the cart drivers and the driving motors and used for controlling the rotating speed adjustment amount of the driving motors delta REFRIGERATOR. Compared with theprior art, the magnetic nail based automatic rail-mounted gantry crane cart positioning control system has the advantages of accurately providing the position of the rail crane cart, being capable offlexibly adjusting the running posture of the rail crane cart and the like.
