摘　　要：本文提出了一种以EP1C3为核心器件.通过VHDL语言实现二输入-输出模糊控制的控制芯片.允许有16条控制规则(可扩展到256条),其模糊推理过程既有并行又有串行,每秒钟可以完成5万次完整的模糊推理运算。该控制芯片可以运用到各种实时性要求高的模糊控制系统中。本文详细介绍了知识库存储、模糊化、模糊推理以及去模糊在FPGA中的实现细节。A fuzzy logic control chip implemented by VHDL language and EP1C3 device is presented. The chip allows two premises one conclusion, and 16 control rules (extended to 256 control rules is possible). The fuzzy inference is processed in parallel and sequence. 50,000 complete inference processes are implemented in per second with 20MHz frequency. This chip is mainly used for the real-time process control and other suitable applications. The implementing details and considerations with FPGA should be paid are presented with fuzzy knowledge base, fuzzification , fuzzy inference engine, defuzzification.
