The invention discloses a double-pendulum crane backstepping sliding mode control method based on a generalized proportional-integral observer, and the method comprises the steps: constructing a dynamic model of a double-pendulum crane system, rewriting the dynamic model of the double-pendulum crane system, and designing the generalized proportional-integral observer; and effectively estimating the lumped interference and the state variable of the double-pendulum crane system by using a generalized proportional-integral observer to obtain an estimation signal, and designing the double-pendulum crane backstepping sliding mode control system according to the estimation signal. According to the double-pendulum crane system model, a generalized proportional-integral observer is designed, the observer can effectively estimate external interference and uncertainty in the model, and the anti-interference capability of the system is improved; and sliding mode surfaces are respectively designed for a drivable state variable and an under-actuated state variable of the system, so that the swinging of a load and a lifting hook is effectively inhibited.
