摘要
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．
The rule base, the inference engine and the mechanism of the self regulation of universe of discourse in the late developed fuzzy expert controller for aluminum reduction cells were elaborated. The inference engine based on approximate reasoning, a kind of inference method of fuzzy expert system, has the advantage of not only processing knowledge of certain or precise type, but also that of uncertain or fuzzy type. The mechanism of the self regulation of universe of discourse can automatically adjust its input fuzzy variables and/or those of output fuzzy variables according to the change of cell state and the transition of control modes, achieving the object of on line modifying the operating points and the dynamic and static performance of the controller efficiently and conveniently. The results of application showed that the control effect was conspicuous.
