Design and implementation of a hybrid fuzzy controller using VHDL

Abstract

It is presented a novel hybrid controller that combines the benefits of classical controllers and fuzzy logic to improve the system response in tracking. The design was developed in VHDL for a posterior FPGA implementation. The code was simulated using Simulink and Xilinx System Generator (XSG) that allows to simulate the code of the final FPGA target. Several comparative experiments in soft-real time were conducted using a geared DC motor and the results are commented. © 2008 Springer-Verlag Berlin Heidelberg.
