摘　　要：采用FPGA芯片设计了纸材上料机直流调速控制系统,提出了预设运行速度曲线实现惯性分离的控制策略,设计了模糊PID双闭环算法,缩短速度上升的时间并提高稳态精度,RS232接口使系统可以多机协同工作,并且通过判断算法解决了卡纸、重张问题。在Quartus Ⅱ 6.0中设计了包括速度电流检测、模糊PID算法、调速给定和RS232的控制核心。试验表明,系统动作准确、反应快速、性能稳定。The DC motor speed control system of paper feeding machine was designed based on FPGA.A control strategy of inertia separation,which machine runs according to a predetermined speed curve,was put forward.The double closed-loop speed regulation algorithm of fuzzy PID was designed to reduce rising time and steady state error.The paper jam and overlapping problems was settled well with a judgment method.A RS232 interface was designed to form a multi-machine cooperation system.The control core,including speed and current detection,fuzzy-PID algorithm,speed setting and RS232,was designed by Quartus II 6.0.Tests results showed that the system has accurate operation,fast response and steady performance.
