基于PID算法的PLC控制系统设计

Design of PLC Controlled System Based on PID Control Function

根据叶片根部缠绕工艺控制要求,给出基于PLC和其模拟量功能模块的PLC控制系统的硬件实现以及PLC功能模块缓冲寄存器参数的设置方法;应用PID算法,实现对模拟量的过程控制;阐述PLC中PID指令的具体应用。该控制系统在生产中获得较好的应用效果。

According control requirement of vane root winding, a control system based on PLC and it＇s function modules was designed. The hardware structure was presented. The setting method of buffer memory parameters of PLC function modules was introduced. The process control of analogue data was realized by applying PID arithmetic. PID instructions of PLC were discussed. The control system has gained good effect in practice.
