A variable structure control of electrode regulator system of arc furnace

本文提出了一种变结构电极调节系统设计方法 ,首先得出电极调节系统模型 ,在此基础上推导出了离散时间模型参考自适应律 ,针对系统对频繁的干扰存在抖动的情况 ,设计一种变结构调节系统 ,利用模糊控制系统抑制抖动 ,仿真表明这种结构既能够保证良好的跟踪特性 ,又能够有效地抑制抖动。

In this paper,a variable structure control of electrode regulator system is presented.First,the model of electrode regulator system is obtained,then the rule of discrete-time model reference adaptive control is proved.Finally,fuzzy control system is designed to restrain dithering.The results of simulation show that this structure has favorable tracking characteristic and capability of restraining dithering.
