摘　　要：主要介绍了混合模糊控制的方案。该方案采用了"短周期"预测炉温的模糊控制策略,将模糊控制和PID控制结合在一起,利用协调因子的在线自整定来确定气体流量,实现了空燃比的自寻优模糊控制。该系统已投入实际运行,具有动态响应好,稳定性高等特点,有较高的实用价值和推广价值。This paper introduces a hybrid fuzzy control system of the shaft furnace Applied the fuzzy controlstrategy to short period prediction of the furnace temperature and Combining fuzzy control with PID- control, the airflux is achieved hy using the on- line self- adjusting capability of the harmoniousfactor; And the self- optimization fuzzy control of the ratio of air to fuel becomes realized. This systemhas been put into practice, featuring with the characteristics of good dynamic response, high stability. Ithas more practical merit and is worthy to be popularized.
