Design and Implementation of Fuzzy Controller on FPGA
Mani Shankar Anand, Barjeev Tyagi · International Journal of Intelligent Systems and Applications · 2012
Fuzzy Logic Controller (FLC) systems have emerged as one of the most promising areas for Industrial Applications.The high ly growth of fu zzy logic applicat ions led to the need of finding efficient way to hardware implementation.Field Programmab le Gate Array (FPGA) is the most important tool for hardware implementation due to low consumption of energy, high speed of operation and large capacity of data storage.In this paper, instead of an introduction to fuzzy logic control methodology, we have demonstrated the implementation of a FLC through the use of the Very high speed integrated circuits Hardware Description Language (VHDL) code.FLC is designed for an armature control DC motor speed control.VHDL has been used to develop FLC on FPGA .A Sugeno type FLC structure has been used to obtain the controller output.The controller algorithm developed synthesized, simu lated and imp lemented on FPGA Spartan 3E xc3s500e-4fg320 board.
