摘要
针对电弧炉电极调节系统具有非线性、大时滞及时变性等特点,提出将先进的模糊控制应用到电弧炉电极调节系统中来改善系统的调节性能。通过数学仿真证明模糊控制调节性能明显优于原来的死区控制。结合PLC的特点以及模糊控制原理,提出了将模糊控制在西门子S7-400中通过软件编程来实现的方法。这样在原来的基础上既能改善系统的调节性能,又不增加硬件设备,降低改造成本。
Aiming at the electrode regulating system of electric arc furnace have the characteristics of non- linearity, long time lag ,time variable,etc,proposed that the advanced fuzzy control was applied to electric arc furnace electrode regulator system to improve the system performance. Proved by mathematical that the simu- lation of fuzzy control regulation is superior to the original dead-time control. According to the features of PLC and the principle of fuzzy control, proposed the method of realizing fuzzy control through software program- ming based on Siemens $7 -400. So on the basis of the original system can improve the regulation, without ad- ditional hardware, to reduce the cost of renovation.
