用于热风炉燃烧系统的模糊控制器

Fuzzy Controller Used in Combustion System of Hot-Blast Stove

针对热风炉燃烧系统的复杂性、参数的不确定性和非线性,结合国内外的操作经验,为该系统研制了带修正因子的自适应模糊控制器。仿真试验与实际运行结果表明,该控制器通过对废气温度变化的控制,可以在满足工艺要求的条件下提高热交换效率、稳定炉况、节约能源、易于实现。

In view of the non-linear, uncertain and complicated characteristics of the combustion system in hot-blast stove, referring to the operating experiences at home and abroad, a fuzzy self-adaptive controller was used for controlling the temperature of the waste gas. The results of simulated and practical application have proved that the system is able to enhance the heat-transfer efficiency, stabilize the furnace condition, economize the energy and simplify the operating procedure.
