摘　　要：在包装机生产线中,特别是在多级传动电动机同步运行控制中,包装材料的准确传送是设备运行的关键。由于包装机生产线复杂,切刀、凸轮等不规则器件比较多,该文采用模糊PID控制算法与PLC控制相结合的设计理念,应用模糊集合理论建立参数,通过查表的方法实现对于不同的误差和误差变化率在线调整比例、积分和微分系数,使其根据对象的变化而变化,以满足工业控制的要求,收到了较为满意的控制效果。In the production line of packing machine, especially in multistage drive motor synchro- nous operation control and accurate transmission of packaging materials is the key of equipment operation. Due to the complexity of the production line of packing machine, cutter, cam and other irregular more device, this paper using fuzzy PID control algorithm and PLC control combination design philosophy, using fuzzy set theory to establish the parameters and through the look -up table method to achieve for different error and error change rate for online tuning proportional change according to the change of the object, in order to meet , integral and differential coefficient of the the requirement of industry control and received satisfactory control effect.
