The invention relates to the technical field of cranes, in particular to a self-adaptive control method and device for a crane rotation system and a crane. During use, when an operator controls an upper vehicle of the crane to execute the rotation action, the pilot valve is started by adopting the pre-calibrated minimum starting current, and then the minimum starting current corresponding to the current working condition state is corrected according to the actual rotation change time and the change rotation angular velocity; the stability and timeliness of one-time rotation action under the working condition state are optimized, and self-adaptive control over the minimum starting current of the rotation system is achieved.

    本申请涉及起重机技术领域,具体涉及起重机回转系统自适应控制方法及装置、起重机。本申请在使用时,在操作手控制起重机上车执行回转动作时,采用预先标定的最小启动电流启动先导阀,然后根据实际的回转变化用时以及变化回转角速度,对当前工况状态对应的最小启动电流进行修正,以优化该工况状态下一次回转动作的平稳性以及及时性,实现对回转系统的最小启动电流的自适应控制。
