Converter steel - making is a complicated diverse high temperature reaction process and the foundation of the model also is a diverse non - linear mapped process . so it is emergent to find a more superior control model abandoned the tradition static model in the condition that many medium and small converter cannot use an assistant gun 转炉炼钢过程是一个复杂的多元多相高温反应过程，其模型的建立则是一个典型的多元非线性的映射过程，尤其在大多中小型转炉不宜增设副枪的条件下，如何在传统的静态模型之外寻找性能更优越的控制模型，就显得比较突出和迫切。
