摘　　要：将模糊控制与滑模控制结合应用于电弧炉电极调节系统中,给出了自适应模糊滑模控制系统的详细设计过程。用自适应模糊控制逼近滑模控制中的不确定参数,加入切换控制以保证滑动条件的成立,推导了规则参数调整的自适应律。在线调节自适应模糊滑模控制器的参数以克服电弧炉电极调节系统的不确定性,具有较强的鲁棒性。仿真结果表明:该控制算法能有效地抑制弧长扰动,从而获得较好的动态性能。The sliding mode control was combined with the fuzzy control and was applied to the electrode regulator systems of arc furnace, and the detailed design procedure of the adaptive fuzzy sliding mode control system was proposed. The adaptive fuzzy control was utilized to approach the uncertain parameter of sliding mode control, a switching-type control was added in order to guarantee the sliding condition, and then the adaptive law was derived. The parameter of the adaptive fuzzy control was adjusted on-line to deal with the electrode regulator systems of arc furnace uncertainty. The results of simulation show that this proposed arithmetic of control can restrain the disturbance of arc length effectively, accordingly obtains much better dynamic characteristics.
