由于模糊控制查询表在模糊控制中有着非常重要的应用,而基于传统利用MATLAB提供的模糊推理系统(FIS)的GUI界面来设计模糊控制查询表耗时较长。本文使用MATLAB设计了一种模糊控制查询表的快速获取方法,并通过该方法与GUI界面设计法获得的模糊控制查询表的比较,说明了该方法的可行性。同时,通过仿真实验验证了该获取模糊控制查询表方法的有效性。最后,将这种快速制取模糊控制查询表的方法应用于造纸污水处理过程中溶解氧浓度的模糊控制设计中。
Because fuzzy control lookup table has very important application in fuzzy control, designing fuzzy control lookup table based on traditional fuzzy reasoning system (FIS) GUI interface provided by MATLAB takes a long time. In this paper, MATLAB is used to design a fast acquisition method of fuzzy control query table. The comparison of fuzzy control lookup tables obtained by this method and GUI interface design method shows the feasibility of this method. At the same time, the validity of the fuzzy control lookup table is verified by simulation experiments. Finally, this method of fuzzy control lookup table is applied to the fuzzy control design of dissolved oxygen concentration in the process of papermaking wastewater treatment.
