| 摘 要： | 为了实现低碳铬铁冶炼时间的必要缩短,分别建立氩氧精炼低碳铬铁过程中碳含量降低速率与温度变化速率与氧气供给速度之间的机理模型方程,且根据不同碳含量阶段的供氧速率构造专家控制系统,实现内模控制器滤波器时间常数的自调节,建立了基于专家内模的氩氧精炼低碳铬铁的碳含量终点控制系统。仿真结果表明:该系统能够在实现内模控制稳态无误差的基础上,进一步提高系统的动态响应,有效缩短了整个氩氧精炼铬铁合金的冶炼时间。在内模控制的基础上结合使用专家控制的方法对解决输出和扰动均不可测一类工业对象的控制问题具有一定借鉴作用。

| Abstract: | In order to ensure the stability of argon-oxygen refining low carbon ferrochromium, which is a very complex process, is not affected by the external unmeasurable disturbance, and further improve the dynamic response ability. In this paper, the end-point control system of carbon content in argon-oxygen refining of low carbon ferrochromium is studied by integrating internal model control method and expert control system. The results show that the system can automatically adjust the filter time constant in IMC. It can be seen that while the stability of the system is guaranteed, the dynamic response of the system is further improved. |
