A Generic Approach to Fuzzy Logic Controller Synthesis on FPGA

This paper presents a general procedure for fuzzy logic controller (FLC) synthesis on field programmable gate arrays (FPGA) devices; the hardware implementation of a simple state machine for data flow control, the VHDL hardware description code of the FLC components, the observed synthesis hardware requirements on a Xilinx Spartan-3 FPGA and executions times achieved, errors due to finite control word length is reported, as well the modifications required in this modular approach to implement a variety of FLC on a readably available FPGA device.
