Decoupled adaptive backstepping control of fractional-order permanent magnet synchronous motor

Abstract

To study the chaotic phenomenon of fractional-order permanent magnet synchronous motor (FOPMSM) and its control problem, a strategy of decoupled adaptive backstepping chaotic control is proposed based on feedback decoupling control for fractional-order permanent magnet synchronous motor (FOPMSM) system to reduce the order, and the adaptive backstepping method is used to design the chaotic controller according to the decoupled system. The fractional-order permanent magnet synchronous motor (FOPMSM) system's stability is analyzed using the Mittag-Leffler stability theorem. The simulation results show that the decoupled adaptive backstepping control can bring the permanent magnet synchronous motor (FOPMSM) out of the chaotic state quickly and with a fast response.
