摘　　要：针对目前铁矿石还原测定系统技术落后、炉温控制精度不高的现状,根据铁矿石还原测定试验的升温特点,对基于工业控制计算机的智能控制算法进行了研究,取代功能简单的传统仪表实现精确的温度控制;系统采用便于计算机编程实现的解析式模糊控制策略,提出对不同温度段使用不同控制规则,并引入自寻优算法,提高了控温精度;试验结果表明,该控制系统具有良好的动静态特性和抗干扰能力,该控制方法可靠有效并具有一定的实用性和借鉴价值。This paper introduces an intelligent control arithmetic for IPC to precisely control the specialty of iron ore reducibility mensuration system in stead of traditional instrument control device, in that the development of mensuration technology for iron ore reducibility is laggard and the temperature control is rough. The new fuzzy control method is based on formula and esay to be programmed by computer. Proper control rules are applied to different temperature segment and the self - optimizing arithmetic makes the temperature control precise. The result of experimentation shows that the system has satisfactory performance and the method is reliable and efficacious. The arithmetic and methods adopted in the system are practical and worthy for reference.
