The invention discloses a crane anti-swing control system capable of improving loading and unloading stability. The crane anti-swing control system capable of improving the loading and unloading stability involves a programmable controller, various mechanism frequency converters and a lifting encoder, wherein all parts are networked by using an EtherNet/IP communication protocol, and operation parameters of a cart mechanism and a trolley mechanism are obtained by obtaining lifting of a bridge crane; the output frequencies of the frequency converters are adjusted in real time to change operation states according to the actual height of load to match the operation parameters of the cart mechanism and the trolley mechanism when the operation mechanism is started and stopped, and the speed curve of the operation mechanism is adjusted in real time according to the calculated load swing parameters. According to the crane anti-swing control system capable of improving the loading and unloading stability, a advanced anti-swing algorithm is adopted, the swing period is measured and calculated according to the simple swing principle, swing estimation is carried out at an initial accelerationand deceleration stage, hanging object swing control is carried out at the middle section and the tail section to achieve the effect of shortening the processing time, the effect of shortening the stopping distance is achieved by adjusting the anti-swing curve and rigidity, compared with a traditional electronic anti-swing system, the system has remarkable advantages in the aspect of shortening the stopping sliding distance of the operation mechanism.
