A bridge crane sliding mode control method based on an unknown input observer technology comprises the steps that a dynamic model of a bridge crane system is established, and the system state and control parameters are initialized; designing an unknown input observer; designing a double-layer hyperbolic reaching law; and designing a sliding mode controller based on the unknown input observer and the double-layer hyperbolic reaching law. The method can effectively solve the problem of quick positioning of the bridge crane under different continuous non-matched disturbance conditions, effectively inhibits the residual swing of the load of the bridge crane, and guarantees the stability of control input.
