介绍了最新开发的铝电解模糊专家控制器的规则库、论域自调整机制以及推理机的构造．采用了基于“近似推理”原理的模糊专家系统的推理技术构造推理机，使其具有同时处理精确知识和模糊知识的优点，并且建立了“论域自调整”机制，使控制器可根据槽况的变化和控制模式的切换，自动调整输入模糊变量和／或输出模糊变量所对应的精确值的论域，从而简便而有效地达到在线自动调整控制器的工作点和动、静态品质的目的．应用结果表明，改进的效果显著．
This paper introduces the newly developed rules base of aluminum electrolysis fuzzy expert controller, the theory of domain self-adjustment and the construction of inference engine. The inference engine is constructed based on the reasoning technology of fuzzy expert system based on the principle of “approximate reasoning” to make it have the advantage of dealing with precise knowledge and fuzzy knowledge at the same time. And the mechanism of “domain self-tuning” is established, And automatically adjust the domain of the precise value corresponding to the input fuzzy variable and / or the output fuzzy variable so as to achieve the purpose of automatically adjusting the working point and the dynamic and static quality of the controller online and easily. The application results show that the improvement effect is remarkable.
