自适应PID控制算法及应用

THE CONTROL ALGORITHM FOR ADAPTIVE PID AND ITS APPLICATION

本文给出了一种自适应PID控制器的设计方法,并用MCS—51系列单片微机实现了这种控制方法。这种控制器具有如下特点:1)实现了控制器参数的在线自动整定;2)与常规PID控制器有相同的结构;3)采用单片微机实现了控制算法,实用性强,可靠性好。

This paper presents the control algorithm for an adaptive PID controller and the implementation of this algorithm in a MCS-51 family single-chip microcomputer.This controller possesses the following characteristics:a)bring- ing about an auto-tuning of the parameters of PID controller on line;b)having the same structure as the PID type;c)being very practical and reliable.
