Abstract :
The relative merits of PI and fuzzy logic speed control algorithms for a vector-controlled PM brushless AC drive system are assessed. An adaptive fuzzy logic control algorithm with dynamically adjusted membership function of the output fuzzy sets is proposed. Its implementation is very simple, and it offers excellent speed control performance and robustness to parameter variations, whilst current harmonics are reduced.
