| 摘 要： | 针对钢坯加热炉系统所具有的典型分布参数特点，提出了一种基于分散推理结构的钢坯温度分布模糊控制方案．首先，将炉内钢坯温度偏差分布作为模糊推理系统的输入信息；然后，对于每一个炉温调整点，通过一组二维模糊控制器，产生一组与钢坯温度偏差分布对应的炉温补偿控制分量；最后，综合各控制分量获得各调整点处的炉温补偿量．仿真算例表明，该方案能够有效地保证钢坯按理想加热曲线完成加热过程．

| Abstract: | Due to the typical distributed parameter characteristics of billet reheating furnace,a fuzzy control method based on decentralized reasoning structure for billet temperature distribution is proposed.For every set-point,the furnace temperature compensation values corresponding to a set of billet temperature deviation distribution are obtained by a set of two-dimensional fuzzy controllers whose input information is the temperature deviation distribution of billets in furnace.Then the furnace temperature compe... |
