本文在分析直热炉燃烧过程中的偏流成因和处理手段的基础上 ,提出模糊控制方案 ,该方案实施后偏流问题得到了彻底的解决。此外本文提出采用离散模糊控制器的新方法 ,完全可以解决其它流体的流量分配控制系统运行中的偏流问题。实际运行表明该方案是合理和有效的 Based on the analysis of the cause and treatment of bias current in the combustion process of a direct heat furnace, a fuzzy control scheme is proposed. After this scheme is implemented, the problem of bias current is completely solved. In addition, this paper proposes a new method using discrete fuzzy controller, which can completely solve the problem of bias current in the operation of other fluid flow distribution control systems. The actual operation shows that the program is reasonable and effective
