Swing generated by the hook during the lifting process of bridge crane must be overcome.Based on the model identification experiment of bridge crane,the dynamic model of bridge crane was obtained by test.In the aspect of antiswing controller design,a method of using generalized predictive control to adjust PID parameters was proposed,so that the traditional PID controller could effectively suppress and eliminate swing of the crane hook.Both simulation and experiment results show that the design method of this PID controller is correct and effective,it is of great significance for realizing unattended automatic control of crane.
