摘　　要：根据实际润叶生产工艺和控制要求,对红塔烟叶复烤线WF300型润叶机电控系统进行改造,针对原有系统控制精度低,滞后及自动监控不完善提出了新的解决方案,建立了加水前馈-串级控制模型;对加料采用批量控制进行实时修正,上述控制方案利用PLC编程实现,并用CITECT开发实时监控程序实现与PLC的数据交互,完成对生产的实时监控,运行情况表明,改造后该系统控制精度提高、可靠性增强、使用更灵活,更好地满足了润叶工艺质量要求。According to the practical manufacture technology and control requirements, the electric control system of WF300 in tobacco Redry production line is improved. An innovative control solution is presented to enhance the control presision, deduce the delay of control, and extend supervisory function. The feed--forword cascade control models of adding water are established, and the amount of additive are refined by batch--control technology. The control solution is implemented by PLC programming, while real--time supervisory programs are developed by Citect to communicate with PLC; the tWO parts are combined to meet the real time supervisory requirement. The better performance is acquired when the improved system runs in real environment.
