结晶器液位控制系统的设计与实现(英文)

Design and Implementation of a Mould Level Control System

提出了一种简单有效的结晶器液位智能控制控制方法 ,它包括一个基于模型降阶和内模控制的非线性滑动水口及其液压机构控制器、一个中间包重量前馈控制器和一个结晶器液位模糊预测控制器 .实验和现场使用表明 ,该方法能够准确可靠地应用于连铸过程控制之中 .

A simple effective intelligent mould level control method is presented. It consistes of a nonlinear controller, for sliding valve and its hydraulic actuator based on model reduction and inner model control, a feed forward tundish weight controller and a mould level predictive fuzzy controller. Its accuracy and reliability for practical use in continuous casting process are demonstrated by satisfactory experimental and on_line control performances.
