模糊控制器在液压控制系统中的应用

Application of Blurring Controller in the Controlling System of Hydraulic Pressure

模糊控制是以模糊集合论、模糊语言变量及模糊逻辑推理为基础的一种计算机数字控制技术。它模拟人对各种系统的控制思维，将熟练操作人员的操作经验总结为一系列具有模糊性的条件语句（控制规则），由计算机执行控制决策．本文论述了模糊控制的基本思想、液压控制系统引入模糊控制的原因及重要性，并举例说明采用软件方法实现模糊控制具有简单经济的特点．

Blurring control is a kind of computer digital controlling technology on the basis of blurring set theory, blurring language variable and blurring logical inference. It simulates human thoughts to various systems and sums up the operator's experlences into a series of blurring conditional sentences(controlling rules) and they are carried out by computer. This article discussed the basic ideas of blurring control, reasons and importance to put hydraulic pressure in the use of blurring control. It illustrated through examples the simplicity and low cost of the realization of blurring control by software.
