These uncertainties are modeled as lumped disturbances within the PMSM drive system. First, the ASMC is developed to enhance speed tracking, while the adaptive reaching law is employed to mitigate chattering and expedite the rise time, ensuring fast convergence to the desired speed. Next, the DPCC is applied to further improve current regulation performance. Additionally, disturbance observer is designed to estimate the lumped disturbances and provide compensation in the speed and current control loop, thereby improving the drive performance robustness. The effectiveness of the proposed ASMC-DPCC method is demonstrated through simulations on in-wheel PMSM motors, showing improved tracking accuracy and disturbance rejection. © 2024 IEEE.adaptive sliding mode control (ASMC)deadbeat predictive current control (DPCC)disturbance observerperma-nent magnet synchronous motor (PMSM)reaching law
