Adaptive Fuzzy Tracking Control for a Permanent Magnet Synchronous Motor via Backstepping Approach

Abstract EN

The speed tracking control problem of permanent magnet synchronous motors with parameter uncertainties and load torque disturbance is addressed.

Fuzzy logic systems are used to approximate nonlinearities, and an adaptive backstepping technique is employed to construct controllers.

The proposed controller guarantees the tracking error convergence to a small neighborhood of the origin and achieves the good tracking performance.

Simulation results clearly show that the proposed control scheme can track the position reference signal generated by a reference model successfully under parameter uncertainties and load torque disturbance without singularity and overparameterization.
