In this work, the problem of design of fuzzy controllers is studied. In a first part, we present a state of art on the techniques used, namely the genetic algorithms and its various alternatives, the neural networks, fuzzy logic and their hybridizations. Taking support on this state of art, we propose a first design method of the fuzzy controllers of Mamdani by simple genetic algorithms. Thereafter, this method is improved by the use of the hierarchical genetic algorithms. These algorithms allow, by the means of the structure of their chromosomes, a better optimization of the controller parameters while eliminating the incoherent rules which can arise, as well as for the first method, at the end of the optimization process. The last method ...
