摘　　要：由于受外部扰动的影响,采用三相异步电动机和凸轮分割器驱动的转盘式自动生产线中,各转盘容易出现失同步问题。针对该问题,结合模糊控制和同步补偿控制原理,提出了一种针对该类型转盘式生产线的同步方法,设计了针对实际生产线的控制架构,并在PLC中实现具体控制算法。从实际运行结果来看,在主电机转速突然下降和突然上升时,从电机对其进行快速跟踪,表明该方法可以有效解决转盘间由于累积误差造成的失同步现象,使得生产连续,生产效率提高。Due to external disturbance, the loss synchronization problem always appears between turntables of the automatic production line which is driven by three phase asynchronous motor and cam partition. To solve this problem, a synchronous method for this type of turntable production line is presented by combining with the fuzzy control and synchronous compensation control principle. The control framework for the practical production line is designed, and the specific control algorithm is achieved in PLC. The actual operating result shows the slave motor can track it immediately as the master motor speed drops and rises suddenly, h shows that the method can effectively solve the loss synchronization phenomenon caused by the cumulative error between turntables, so as to keep the production continuous and improve the production efficiency.
