The accuracy of motor control systems is crucial for improving energy efficiency and production quality. However, traditional motor control methods suffer from slow response and weak anti-interference ability, which limits their performance in modern industrial applications. To optimize the dynamic performance of the motor control system, a motor control algorithm combining model predictive control and disturbance compensator is proposed. The composite control strategy based on model predictive and disturbance compensator had the shortest rise time and settling time in all speed stages. When the speed was 2,000 rpm, the rise time and settling time were 0.72 s and 1.89 s, respectively. Under different stages of friction torque disturbance in bearings, the steady-state error offset of the composite control strategy was minimized. When the rated torque was 20%, the steady-state error offset was 2.64%. The proposed motor control algorithm combining model predictive and disturbance compensator can effectively improve the accuracy and stability, providing effective technical solutions for motor control.
