Two important properties of cartesian closed domain categories
范畴的两个重要性质
The software matlab is used to calculate the fuzzy system , the fuzzy system divide the voltage - reactive pane into nine fuzzy zone , in this way the domain - swing between closing domain is eliminated
该模糊推理系统的隶属度函数采用三角形隶属度函数，模糊推理采用mamdani型推理，非模糊化采用的是重心法，在设计时使用matlab为辅助进行离线计算。
In this thesis a fuzzy control system used in voltage and reactive power auto regulatory device is designed based on the nine - zone controlling principle . in the fuzzy system , the fuzzy reasoning is mamdani method and the antifuzzy is centroid method . the software matlab is used to calculate the fuzzy system . the fuzzy system divide the voltage - reactive pane into fuzzy zone , in this way the domain - swing between closing domain is eliminated
论文对电压无功综合控制技术进行研究，针对传统九区域分区控制方法无视电压与无功耦合的缺点，结合变电站电压无功控制的实践经验，在传统控制方法上引入模糊控制，设计了基于模糊控制的电压无功综合控制系统。模糊推理系统中采用mamdani型推理，非模糊化采用重心法，设计中使用matlab进行辅助设计和离线计算。
