Design of intelligent controller for temperature process on FPGA

This paper investigates about the execution of fuzzy logic controller (FLC) on reconfigurable device. The reconfigurable device programmed was Field Programmable Gate Array (FPGA). The synthesis and simulations were carried out using Altera Quartus II software tool. The coding for the logic cells configuration was carried out with Very High Speed Hardware Description Language (VHDL). The effective implementation of FPGA was noted with less logical elements (LEs) count, the modules were configured with FLC algorithm using Mamdani's function. This paper projects the complete synthesis of VHDL program for fuzzy logic control algorithm with the mathematical model for heat exchanger process under different input conditions. The functionality of the fuzzy controller was verified on the FPGA chip.
