摘　　要：在高精度行车起重机多轴同步控制系统中,同步控制的最终目标在于降低同步误差与跟踪误差。然而,实际应用中,受限于外部硬件条件,同步误差和跟踪误差往往不可避免,甚至需要主动调节。针对实际工况,采用西门子PLC控制系统和S120伺服驱动系统对行车起重机四轴行走进行控制,通过简化和改进控制结构,将四轴同步优化成双轴同步与双轴速度跟随。经现场验证,该方法在简化算法的同时,显著提升了设备运行的容错性,可为类似高精度多轴控制的应用场景提供参考。In the multi-axis synchronization system of high-precision travelling crane,the ultimate goal of synchronization is to reduce synchronization errors and tracking errors.However,limited by external hardware conditions in practice,synchronization errors and tracking errors are often unavoidable,and even need to be actively adjusted.Siemens PLC control system and S120 servo drive system are adopted to control the four-axis travel of travelling crane according to the actual working conditions,and the four-axis synchronization is optimized into two-axis synchronization and two-axis speed tracking by simplifying and improving the control structure.As verified on site,the method significantly improves the fault tolerance of equipment operation while simplifying the algorithm,which can provide a reference for similar high-precision multi-axis control application scenarios.
