摘　　要：基于全部模糊控制规则的模糊逻辑推理软件化实现方法有时难以满足快时变过程控制的要求,而基于部分规则的模糊推理硬件化实现方法则具有非常高的推理速度,从而提出了一种基于作用模糊子集推理的数/模混合推理结构,讨论了其实现原理,设计了电路原理图.该结构对于多输入系统及拥有大量规则的系统,不仅不减缓推理速度,而且可以节省芯片面积.The reasoning speed based on fuzzy inference by hardware possesses is very high. Furthermore, not all the fuzzy rules have contribution to the result in a reference. An analogue/digital hybrid inference construction, based on functioning-fuzzy-subset inference, has been developed, and its principle of hardware implementation has been discussed and the circuit diagram in principle of the hybrid inference construction has been presented as well. Experiments show that for the multi-input system and the system with a large number of fuzzy control rules, the construction will not slow down the reasoning speed, but in reverse it will save the chip area largely.
