Control of Regulator System of Arc Furnace Based on Feedback Linearization

讨论了反馈线性化方法在在非线性系统控制中的应用。以单相电弧炉电极调节系统为被控对象,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线性系统,然后设计控制器,并以此进行了MATLAB仿真。仿真结果表明,具有跟踪精度高、反应速度快的反馈线性化控制方法,应用于电弧炉电极调节系统的控制中是可行的、有效的。

The application of feedback linearization in the nonlinear systems control was discussed. An investigation was made to the single-phase electrode regulator system of arc furnace. Based on the feedback linearization procedure of differential geometry, an equivalent, fully controllable and linear model was derived via a homomorphic transformation and a controller was constructed for the system. The simulation was achieved by using MATLAB. The results show the controller with well tracking accuracy, rapid response is efficient in controlling the electrode regulator system of arc furnace.
