Abstract:

In this paper, a new control strategy is developed;
an adaptive fuzzy controller based on Lyapunov’s
stability theory (AFLC) recalculates the real-time PI-fuzzy
gains and combines the advantages of two robust techniques
i.e. the fuzzy logic control and the adaptive one. For the new
adaptive fuzzy control, we followed two steps: in the first one, a
PI-fuzzy controller is designed, in the second step, the gains of
a fuzzy regulator are determined. Extensive simulation results
are presented to validate the proposed technique. The system is
tested at different speeds and a very satisfactory performance
has been achieved.
