Embedded system based on a real time fuzzy motor speed controller

(in lingua inglese)

The main contribution of this work is to present an approach of real time fuzzy logic controller for DC motor using VHDL description and FPGA technology. FLC based on FPGA has some advantages such as flexible design (the membership functions and rule base can be easily changed), feature accuracy, high reliability, cost improvement, and high speed. The performance of the FLC is compared with the PI controller for reference speed and load changes.
