一种简单的比例积分可拓控制器

运用比例积分型提出一种简单可拓控制器。以可拓集合为基础，研究了一种确定控制量的新方法。该方法首先在某些区域内对涉及可拓函数的论域进行划分并作标记。所得的控制结果是分级可拓函数及其标数的线性组合。从本质上看，专家知识和熟练技术人员的经验可嵌入可拓控制器设计之中，可以说，可拓控制器的设计比模糊控制器的设计要容易得多。最后，把所提出的可拓控制器用于一个线性过程控制，并验证了控制的效果和性能。

A Simple PI-Extension Controller

A simple extension controller,using the type of Proportional Integral(PI),is proposed.On the basis of the concept of extension set.A novel method for determining the amount of control will be discussed.The universe of discourse regarding to the defined extension dependent function can be firstly partitioned and labeled in some regions.We then show that the resulting control is the linear combination of the grade of extension dependent function and the labeled number.Essentially,the expert knowledge and the experience of a skill operator can be embedded in extension controller design.Broadly speaking,the design of extension controller is easily than that of fuzzy controller.Finally,the proposed simple extension controller is used to control a linear process,and its effectiveness and ability is verified.
