摘　　要：主要介绍了在模拟量的闭环控制系统中可编程控制器(PLC)的数字PID控制程序设计,在确定PID控制算法的基础上,根据PLC的特点,重点介绍了PLC程序编制和程序调试分析,并采用PID控制的响应曲线验证了程序的正确性。In industrial process control system, PID control is still one of the most widely applied control methods. This paper primarily introduced the program design of the arithmetic PID of Programmable Controller in shut-ring control system of imitation control . According to the PID control and PLC characteristics, the method of drawing up program and the method of trying the program were introduced. The reasonableness of PLC program was verified by the response curve of PID control.

关 键 词：PLC 数字PID控制算法 程序设计 可编程控制器 参数整定
