阐述了电动铲运机卷缆同步中存在的问题及研究意义,分析了卷缆控制系统的工作特点,进行了同步控制策略的研究,提出并讨论了速度匹配、拖放长度保持和张力保持这3种控制方式的利弊。基于张力保持方式设计了模糊PID参数自整定控制系统,并进行了应用测试。结果表明,该控制系统性能优越、响应快速、控制精确,使电缆张力紧密跟随设定目标变化及保持,实现了卷缆与车速的同步,可为相关卷扬类动作的控制提供参考。
The problems existing in the synchronization of electric shovel winches and their research significance are expounded. The working characteristics of the cable control system are analyzed. The synchronization control strategy is studied. The speed matching, drag and drop length holding and tension holding are discussed and discussed. The pros and cons of three control methods. The fuzzy PID parameter self-tuning control system is designed based on the tension maintaining method, and the application test is carried out. The results show that the control system is superior in performance, fast in response and precise in control. The tension of the cable follows closely the change and retention of the target and the synchronization between the cable and the vehicle speed is achieved.
