Fuzzy logic control has been studied extensively and has been applied in various applications. The most popular control strategy takes the Fuzzy Proportional-Integral (FPI) form. While systematic methods have been developed to derive the fuzzy rules and membership functions, the choice of the scaling factors remains an open problem. In this paper, an analytical FPI scaling factor determining method is derived, based on the fictional equivalence of the PI and FPI controllers. Simulations and experiments have been carried out with a permanent magnet synchronous motor (PMSM) drive system as test-bed, the obtained results have verified that the derived method is applicable to both the initial choice and further tuning of the FPI scaling factors.

Abstract
Fuzzy logic control has been studied extensively and has been applied in various applications. The most popular control strategy takes the Fuzzy Proportional-Integral (FPI) form. While systematic methods have been developed to derive the fuzzy rules and membership functions, the choice of the scaling factors remains an open problem. In this paper, an analytical FPI scaling factor determining method is derived, based on the fictional equivalence of the PI and FPI controllers. Simulations and experiments have been carried out with a permanent magnet synchronous motor (PMSM) drive system as test-bed, the obtained results have verified that the derived method is applicable to both the initial choice and further tuning of the FPI scaling factors.Pubblicazioni consigliate
