摘　　要：讨论反馈线性化方法在单相电弧炉电极调节系统控制中的应用。在存在弧长扰动的情况下,应用基于微分几何的线性反馈方法将原非线性系统等价为完全可控的线性系统,以此设计控制器,并进行了Matlab仿真。仿真结果表明,具有跟踪精度高、反应速度快、鲁棒性强特性的反馈线性化控制方法,在单相电弧炉电极调节系统输出跟踪控制中应用后,控制效果良好。Application of feedback linearization method in control of single-phase arc furnace electrode regulator system is discussed. In the presence of arc length disturbance circumstance, linear feedback method based on differential geometry was adopted to make original non-linear system equivalent to full controllable linear system. Based on it, a controller was designed and simulation was completed by Matlab. Simulation results show that feedback linearization control method is characterized by high tracking accuracy,fast response speed and strong robust in single-phase are furnace electrode regulator system output tracking control. Its control effect is good.
