摘要
依据人造板连续压机热压压力控制的原理,利用欧姆龙PLC并结合压力传感器实现了压力自动控制;编写控制程序并采用模糊PID算法调节参数达到了压力的较为精确的控制;利用NP designer编程软件设计了人机监控界面,达到对热压压力进行实时监控。该控制系统可以实现生产过程连续性,提高自动化程度。模糊PID控制方法的应用有利于提高人造板产品的质量及生产效率。
based on the control principle for the wood-based panels＇ continual hot-press,this article achieved the pressure automatic control by using OMRON PLC and pressure transducers,compiled the control programs,achieved more accurate control request in pressure automatic control by proposing the fuzzy PID control method,designed Man-Machine by NP designer to make real-time supervise for hot press pressure.This system can realize continuous production process and improve the automation.The use of fuzzy PID is conducive to improving the quality of wood products and production efficiency.
