数字PID调节器的一种改进算法

An Improved Arithmetic Approach of Digital PID Regulator

在积分分离的PID改进算法基础上,提出一种根据偏差绝对值大小和变化方向进行调节器参数修正的PID控制算法。在火力发电机组控制系统仿真软件开发过程中,该算法得到充分应用,取得很好效果。

A PID controlling arithmetic approach, based on an improved PID arithmetic approach in which integral is separated, has been brought forward, which modifies regulator parameter according to absolute value magnitude and changing direction of error of quantity regulated. This arithmetic approach has been applied well in simulation software of thermal power unit control system for many years. It’s confirmed by research that this arithmetic method is applied well not only in simulation software, but also in industry process auto-control.
