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. According to the characteristic of the typical distribution parameters of billet heating furnace system, a fuzzy control scheme of billet temperature distribution based on distributed reasoning structure is proposed.Firstly, the deviation distribution of furnace billet temperature is taken as the input information of fuzzy inference system. Then, A set of furnace temperature adjustment points, through a set of two-dimensional fuzzy controller, generates a set of furnace temperature compensation control components corresponding to the temperature deviation distribution of billet. Finally, the temperature compensation amount at each adjustment point is obtained by synthesizing the control components. Example shows that the program can effectively ensure the ideal heating curve to complete the heating process billet.
