Implication

This research demonstrates improved speed regulation in PMSM drives using advanced control strategies, suggesting better performance under load disturbances.

Key Points

To enhance dynamic response and robustness of PMSM speed regulation under load disturbances through a novel control strategy.
Proposed a composite control strategy integrating NSMC and HDOB.
Designed an adaptive reaching law for faster convergence.
Developed an adaptive saturation function to reduce chattering.
Implemented real-time disturbance estimation for effective disturbance rejection.
Validated effectiveness through simulations and real-time experiments.
NSMC reduced settling time by 43.1% compared to conventional sliding mode control at 600 r/min.
Eliminated overshoot during speed variations.
Reduced maximum speed deviation by 38.3% under sudden load application and 57.2% under load removal compared to SMC + HDOB.
Achieved faster speed tracking and smaller speed fluctuations.
