模糊PID控制器的设计研究

本文以数字ＰＩＤ控制器为基础，引入模糊集合论，将ＰＩＤ参数动态变化，介绍了一种新的模糊ＰＩＤ控制器。着重对模糊ＰＩＤ控制器的结构、原理、设计原则和步骤进行了叙述。研究结果表明，与数字ＰＩＤ控制器相比，模糊ＰＩＤ控制器的动态品质较优，适应性更强。

An Approach to the Design of Fuzzy PID Contorller

Based on the digital PID controller,introducing fuzzy sets and varying param-eters of the PID controller dynamically.this paper presents a new fyzzy PID controller. Theauthor has mainly stated its structure and principles,analyzzd the principle and procedure ofits design, Research restilts indicate that the fuzzy PID controller hats a better dynamic quali-ties and adaptability,as conipared with the digital PID controller.
