Digital Fuzzy Logic Controller using VHDL
S. P. Joy Vasantha Rani, Pradeep Mohan Kumar Kanagasabapathy, Aman Kumar · 2006
The hardware implementation of fuzzy logic controller(FLC) on FPGA is very important because of the increasing number of fuzzy applications requiring highly parallel and high speed fuzzy processing. This paper describes the hardware implementation of two input, one output fuzzy logic controller using VHDL. The architectural design is tested using Spartan FPGA chip xc2s300e-pq208. The maximum frequency of the clock running the FLC and the total number of gates required for the hardware implementation of fuzzy logic controller are compared for the proportionally increasing number of rules.
