**Robust adaptive fuzzy control of chaos in the permanent magnet synchronous motor.**
*(English)*
Zbl 1205.93092

Summary: An adaptive fuzzy control method is developed to control chaos in the Permanent Magnet Synchronous Motor (PMSM) drive system via backstepping. Fuzzy logic systems are used to approximate unknown nonlinearities, and an adaptive backstepping technique is employed to construct controllers. The proposed controller can suppress the chaos of PMSM and track the reference signal successfully. The simulation results illustrate its effectiveness.
