摘要
该文指出了硬件实现模糊控制表查询电路存在结构复杂、用数字式实现时设计困难等问题,提出了将模糊控制表转换为多值K图,利用K图从开关级设计模糊控制表查询电路的方法,并用此方法具体设计了一个论域元素个数为5的ECL模糊控制表查询电路。从设计实例看,该文提出的设计方法简单易行,而设计的ECL查询电路具有结构简单和高速推理的优点。
Starting from the problem of complicated structure and difficult design using digital circuits in hardware implemention of fuzzy control table, a method for converting the fuzzy control table to K-map of multivalued logic and designing fuzzy control table look-up circuit at switch-level using the K-map is proposed. Using the method, the ECL circuit for implementing the table of the universe composed of five elements is designed. The example shows that the method has the characteristics of simple and feasible, and the designed ECL circuit has simple structure and high-speed inference ability.
