An intelligent optimization control method for the electrode current of submerged arc furnace based on case reasoning is proposed in this article, which is used to realize the automatic control of the electrode control system of the submerged arc furnace. First, the optimization model of electrode current setting value of the submerged arc furnace is established by the case-based reasoning method, and the corresponding electrode current value is calculated to maximize the yield in the safe power range of the furnace. Next, a three-phase electrode current decoupling controller is designed based on fuzzy rules. Finally, an intelligent optimization control system of three-phase electrode current of submerged arc furnace is designed and its superiority is verified by comparison with the proportional\u2013integral\u2013derivative controller. The designed control system has been applied to the smelting production of submerged arc furnace in a domestic smelter. The simulation and industrial operation results show that the system realizes automatic balance adjustment of electrode current of submerged arc furnace under normal working conditions, which greatly reduces the labor intensity of the operator, increases the smelting yield, reduces the unit energy consumption, and brings significant economic and social benefits to the enterprise.<\/jats:p>","DOI":"10.1177\/0959651820906000","type":"journal-article","created":{"date-parts":[[2020,4,6]],"date-time":"2020-04-06T04:32:58Z","timestamp":1586147578000},"page":"1088-1100","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["An intelligent optimization control method for the electrode current of submerged arc furnaces based on case reasoning"],"prefix":"10.1177","volume":"234","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2971-1829","authenticated-orcid":false,"given":"Jianjun","family":"He","sequence":"first","affiliation":[{"name":"School of Automation, Central South University, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2113-1064","authenticated-orcid":false,"given":"Chang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Automation, Central South University, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Automation, Central South University, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ling","family":"Shen","sequence":"additional","affiliation":[{"name":"School of Automation, Central South University, Changsha, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mande","family":"Jing","sequence":"additional","affiliation":[{"name":"State Grid Qinghai Power Energy-Saving Service Co.
