摘要
针对电弧炉冶炼生产过程多变量耦合、时变非线性、大时延和强干扰等特点,采用了温度控制外环和电流平衡控制内环的双环路结构,并实现了电弧炉温度和电流平衡的智能集成控制。该控制系统有效地保证了电弧炉三相电流的平衡和生产工艺对温度的需求,提高了冶炼生产的自动化程度并保证了冶炼生产工艺的稳定性,获得很好的经济效益。
Aimed at characters of large-power EAF's smelt procedure, this paper implements intelligence intergrated control system, by using double closed loops' structure: the inner current loop and the outer temperature loop. This control system assures three phase current balance and temperature stabilization effectively, improves the level of automation in smelt production and assures the stabliziation, achieves good economy benefit.
