Indirect adaptive Fuzzy robust control of arc furnace

针对三相电弧炉电极调节系统的电极控制问题,设计了自适应模糊鲁棒控制器,给出了模糊鲁棒控制系统的详细设计过程。该方法考虑了跟踪误差和逼近误差对参数自适应律的影响,并对模糊逼近误差和外扰采用H∞补偿控制。仿真结果表明:该控制算法具有较好的动态响应和稳态控制精度,对外界干扰及结构参数不确定性具有很强的鲁棒性。

An adaptive fuzzy robust controller is designed to improve the electrode control of three- phase electric arc furnace electrode regulator system. The design process of robust fuzzy control system is proposed in detail. The impacts of tracking error and approximate error on parameter adaptive law are considered. The approximate error and external disturbances H^∞ compensate controls are adopted. The simulation results show that this control algorithm has good dynamic response and stable-control accuracy, as well as a strong robustness for external disturbances and structural parameter uncertainty.
