Abstract: A bridge crane anti-swing method, apparatus, and device based on a sliding mode surface, and a storage medium. After a trolley position subsystem controller and a load swing angle subsystem controller are designed layer by layer on the basis of a backstepping control algorithm, the trolley position subsystem controller and the load swing angle subsystem controller are combined to construct a position swing angle global sliding mode surface; a time-varying function is introduced into the design of a sliding mode surface to construct a position swing angle controller; on the basis of a backstepping sliding mode control theory, a rope length controller is designed layer by layer by combining a state space function of a rope length with a Lyapunov function, and thus, the asymptotical stability of a lifting rope subsystem is realized. The present method not only can solve the unmatched uncertainty problem of a system and maximally eliminate a chattering phenomenon existing in a traditional sliding mode control algorithm, but also can improve the robustness of the anti-swing control of a crane system, and make the system have an anti-interference capability, thereby further improving the stability and control performance of a bridge crane system.
