Abstract： In order to address the issues of poor anti-interference performance， slow response speed，and parameter perturbation in the speed control loop of traditional interior permanent magnet synchronous motor （IPMSM） flux-weakening control strategies， this paper proposes a sliding mode control（SMC） strategy utilizing an enhanced reaching law and adisturbance observer.The enhanced reaching law effectively mitigated control signal chattering and reduced the time for the system trajectory to attain the sliding mode surface. Additionally，the designed sliding mode disturbance observer（SMDO）accurately estimatedunknown disturbances，alowing for adequate compensation in the new sliding mode controler （NSMC）and reducing speed response overshoot during abrupt load transients. Simulation results demonstrated that the proposed control strategy significantly improves response speed，anti-interference capability，and chattering suppression.
