一种新的PID调节器参数自整定方法

A New Method of Auto-tuning PID Reguktor Parameters

本文提出一种从对象阶跃响应提取特征参数的方法,在分析控制系统鲁棒性基础上,结合此特征参数给出了一种机理完善的PID 调节器参数自整定方法,在一定程度上解决了对象模型不确定性问题。

This paper presents new method to obtain process characteristic parameters from unit step response of a plant, and on the base of analysing robustness of control systems, provides a simple and practicable method of auto-tuning PID regulator parameters using process characteristic parameters, which overomes the problem of model uncertainty of plant to some extent. Many simulation results show that the method posscasen enough cred-ibility.
