针对广义控制对象的一维鲁棒PID控制器

在现代鲁棒控制理论基础上，针对广义控制对象提出一种一维鲁棒ＰＩＤ控制器设计方法，其优点是控制器参数可以解析得到，控制器只有一个可调的参数，被调参数与系统的鲁棒性有直接的联系，特别地控制器可以很好地用于大纯滞后控制对象。仿真结果表明本文方法与其他方法相比具有本质的改进。

1 DIMENSION ROBUST PID CONTROLLER BASED ON GENERAL PLANT

An 1 dimension robust PID controller design procedure is developed for the general plant on the basis of modern robust control theory.It has several advantages.First,the parameters of PID controller can be obtained analytically.Second,the controller has only one adjustable parameter which is related to system robustness directly.Finally,the controller can be used for plants with large time delay.The results are compared with those of conventional techniques which suggests that this method ensures good performance and robustness.
