Hardware implementation of fuzzy logic controller

Fuzzy logic controllers are generally implemented on microprocessors which offer a smooth design surface. The purpose of this article is the implementation of a fuzzy logic controller on a field programmable gate array. The use of field programmable gate array gives the designers the possibility to implement a wide variety of applications, test them and make modifications easily and quickly. Two approaches of fuzzy logic controller implementation are proposed. The first one traduces the whole fuzzy logic algorithm to a high description language and the second one is based on the use of the look up table in order to reduce time treatment.
