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-fuzzygains and combines the advantages of

two robust techniquesi.e. the fuzzy logic control

and the adaptive one. For the newadaptive fuzzy

control, we followed two steps: in the first one, a
PI-fuzzy controller is designed, in the second step,

the gains ofa fuzzy regulator are determined.

Extensive simulation resultsare presented to

validate the proposed technique. The system is

tested at different speeds and a very satisfactory

performance has been achieved.
