摘要

Position tracking control for the chaotic Permanent magnet synchronous motor drive system with parameter uncertainties is addressed. Fuzzy logic systems are used to approximate the nonlinearities and adaptive backstepping technique is employed to construct controllers. The proposed adaptive fuzzy controllers guarantee that the tracking error converges to a small neighborhood of the origin. Simulation results show that the proposed control scheme can suppress the chaos of PMSM and guarantees the perfect tracking performance in spite of the existence of the unknown parameters.
