Abstract

This paper proposes a sliding-mode variable structure controller (SMC) based on a disturbance observer for BLDC motors. The SMC exhibits strong insensitivity to turbulence, effectively suppressing disturbances in the BLDCM system. To further enhance performance, a novel variable exponent reaching law is designed, significantly reducing chattering. Additionally, a disturbance observer is integrated to eliminate steady-state errors, improving control precision. Simulation results demonstrate that the proposed SMC achieves superior control performance for BLDCM, along with excellent robustness against external disturbances.
