热工非最小相位对象工程控制及整定方法
Engineering control and tuning method for thermal non-minimum phase plant
摘要
Abstract
The non-minimum phase plants with unstable zeros exists widely in the process of power production.Because of the non-minimum phase characteristics,the control system should ensure internal stability while completing output tracking,and improve response speed while overcoming the undershoot.The general PID control cannot meet the requirements of engineering applications.An engineering control and tuning method for non-minimum phase plants is proposed in this paper.Firstly,a robust PID controller is designed to ensure the stability of the closed-loop control system and overcome the under shoot of the system.Secondly,design a second-order filter that includes system position error,velocity error,and acceleration error to improve the response speed and dynamic performance of the control system.This method is simple,easy to tune,easy to configure in DCS,and has strong robustness to model uncertainty,which is worth promoting in engineering.关键词
