| description | The invention provides a falling amplitude control method, device and system and a crane, and relates to the technical field of engineering control, the method comprises the following steps: acquiring rodless cavity pressure sampling data, arm length sampling data and cargo boom angle sampling data corresponding to a target sampling moment of the crane; based on the rodless cavity pressure sampling data, the arm length sampling data and the cargo boom angle sampling data, a current compensation coefficient corresponding to the cargo boom at the target sampling moment is determined; determining a target falling amplitude control current corresponding to the target sampling moment based on a target handle opening degree and the current compensation coefficient; and controlling the falling amplitude of the cargo boom in a target control period corresponding to the target sampling moment based on the target falling amplitude control current. According to the invention, self-adaptive control of the amplitude falli |
