摘　　要：针对电弧炉电极调节系统具有非线性、时变性、三相耦合等特性,采用无模型自适应控制方法,利用被控对象的I/O数据,不需要系统的数学模型,避免了复杂的建模过程和繁琐的参数整定过程。根据控制律和参数估计算法得到无模型自适应控制方案,利用MATLAB工具搭建三相电弧炉系统进行研究与仿真,仿真结果表明无模型自适应控制具有超调量小、调节时间短以及抗干扰能力强等优点。Aiming at the difficulties of arc furnace electrode regulator system which is non-linear, time-varying and three-phase coupling, a model-free adaptive control method is aaplied. The I/O data of the controlled system is used with no need of mathematical model of the system, so the complex process of modeling and the process of the complex parameter setting are avoided. The model-free adaptive control scheme is set up based on the control law and parameter estimation algorithm. Research and simulation of three phase electric arc furnace system with MATLAB tool show that this approach has the advantages of small overshoot, short regulation time and strong anti-interference ability.
