The invention relates to the technical field of crane control, and discloses a crane double-winch synchronous control method which comprises the following steps: acquiring working condition data of double winches of a crane in real time, calculating a rotating speed synchronous error and a displacement error of the double winches of the crane, and inputting the working condition data of the double winches of the crane into a pre-trained decision tree working condition classification model; outputting a working condition type, and calling a corresponding synchronous control model based on an LSTM neural network model trained for various working conditions according to the working condition type; and based on the monitored synchronous rotating speed error and synchronous displacement error, if the synchronous rotating speed error and the synchronous displacement error are smaller than the expected control precision, further finely adjusting the control parameters, re-examining the accuracy of the decision tree working condition classification model and the LSTM neural network synchronous control model, and optimizing and improving the models.

    本发明涉及起重机控制技术领域,公开了一种起重机双卷扬同步控制方法,包括:通过实时采集起重机双卷扬的工况数据,计算起重机双卷扬的转速同步误差和位移误差,将起重机双卷扬的工况数据输入预训练的决策树工况分类模型,输出工况类型,根据工况类别,基于针对多种工况训练的LSTM神经网络模型调用对应的同步控制模型;基于监测得到的同步转速误差与同步位移误差,若同步转速误差与同步位移误差小于预期的控制精度,进一步微调控制参数,并重新审视决策树工况分类模型和LSTM神经网络同步控制模型的准确性,对模型进行优化和改进。
