中文摘要：

模糊控制作为现代控制理论的一种重要方法,通常以软件编程的方式在算法级上实现.为了在RTL级上实现模糊控制,提出了一种以EP2C5为核心器件,通过VHDL语言实现二输入一输出模糊控制器的方法,并对模糊控制的主要流程进行分析,采用自顶向下、模块化的FPGA设计方法,在Quartus Ⅱ平台上分别对模糊化、模糊推理、解模糊等模块以及顶层设计进行了仿真,最终将其结果与理论值进行对比,仿真结果表明它们之间的误差较小,在允许的误差范围内,验证了该方法的可行性和正确性.

英文摘要：

Fuzzy control,as a kind of important modern control methods,is usually achieved at algorithm-level by software programming.In order to achieve two-premises one-conclusion fuzzy control at RTL-level,a method with VHDL language and EP2C5 device is presented.Through the analysis of a fuzzy control process,fuzzification,fuzzy inference,defuzzification and top-level design are realized respectively by using the top-down and modularization design method of FPGA in Quartus Ⅱ platform.The error between its results and the theoretical values is small,within the permissible error range.The comparative results verify that the method is correct and feasible.
