摘要
PLC(可编程控制器)具有简单易懂、稳定性好、使用寿命长等优点,是目前主要工业控制设备之一。PID控制是迄今为止最通用的控制方法,大多数反馈回路用该方法或其较小的变形来控制。滤池的主要功能是对水中的悬浮物进行过滤,以便得到浊度更低的水,提高出水水质。通过PLC的PID控制器可实现滤池恒水位控制,而恒水位控制可以较好地实现滤池的过滤功能。
Because PLC is easy,stable and has a long service life,it is one of the most important industrial control equipment.PID control is the most common control method up until now;the great majority feedback loop is controlled by this method or its small deformation.Filtering the suspended substance is the main function of filter,in order to obtain cleaner water and improve water quality.The control for constant water level can be fulfilled with PID controller of PLC.Filter works better with constant water level.
