Design of a fuzzy controller with normalization circuits

Abstract

Novel fuzzy logic circuits for composing a fuzzy controller based on fuzzy inference are presented. The circuits consist of membership function circuits. MIN operation circuits, and normalization circuits using current-mode bipolar transistors. Normalization circuits are used as a defuzzifier without dividers. Simulation results demonstrating the functionality of the circuits are reported. The results show the normal and high-speed operation of the circuits.<>
