摘要
为解决模糊控制器电路设计中的去模糊运算问题,提出了一种数模混合电路实现的模糊控制器去模糊运算单元电路设计。通过对折叠型G ilbert乘法器电路作适当的扩展,提出了多路乘法器的设计,实现了多个输入电压与一个共同的乘数电压的乘法运算,并应用该多路乘法器和运算放大器设计了归一化激活度计算电路。应用归一化激活度计算电路和加权求和电路组成了该新结构的去模糊单元电路。采用无锡上华0.6μm混合信号工艺参数设计完成。H sp ice模拟结果表明该单元电路可以完成去模糊运算工作,并作为子单元电路应用于模糊控制器的VLS I实现。
A fuzzy logic controller defuzzier was designed based on the transformation of a folded Gilbert multiplier circuit. The multi-access multiplier was designed to realize a multiplication operation between a single multiplicator and a group of multiplicands using the multi access multiplier. The defuzzier is based on a normalization circuit and a weighted-sum circuit. The circuit was designed using Wuxi Shanghua 0.6μm mixed signal process transistor parameters. Hspice simulations indicate that the circuit provides defuzzification and can be used in VLSI implementations of fuzzy logic controllers.
