为了对铝电解过程控制系统中称为“槽控机”的基本控制单元进行升级改造 ,应用模糊专家控制技术开发了一种称为“模糊专家控制器”的新型控制算法。它的基于“近似推理”原理的推理机具有同时处理精确知识和模糊知识的优点 ,而它的“论域自调整”机制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
In order to upgrade the basic control unit called “tank control machine” in aluminum electrolytic process control system, a new control algorithm called “fuzzy expert controller” was developed by using fuzzy expert control technology. Its reasoning machine based on the principle of “approximate reasoning” has the advantage of dealing with accurate knowledge and fuzzy knowledge at the same time, and its “domain self-tuning” mechanism can automatically adjust the input fuzzy variables according to the change of slot conditions and the switching of control modes / Or outputs the domain of the exact value corresponding to the fuzzy variable, so as to achieve the purpose of automatically adjusting the working point and the moving and the static quality of the controller on line automatically and effectively
