中文摘要: 针对现代电厂运行工况变化频繁，存在严重的动态时变非线性影响因素，提出了一种模糊参数自调整PID控制器，用以改善自动控制系统。该控制器的参数运用模糊推理方法，并能按照控制系统状态及运行工况的变化情况，自动地在线调整PID参数。文中介绍了该方法的基本原理，并给出一些仿真研究的结果。

Abstract:In this paper,a new tuning method based on the specified margin is proposed to determine the parameters of the new fuzzy self-adjusting PID controllers,which are used for control of superheated steam temperatures,and to cope with the situation of modern power plants with working condition changing frequently and strong steam temperature dynamic time-varying nonlinear property.Using the fuzzy inference method,the PID parameters can adaptively be adjusted on line for varying the state of the system and changing the operating condition.The basic ideas are illustrated by some simulations
