Permanent magnet brushless DC motors had been widely used in daily life and industrial fields. With the continuous improvement of control requirements, the traditional doubleclosedloop permanent magnet brushless motor control system had gradually failed to meet the actual needs. Aiming at the control requirements, a driving method combining the internal model control and the fuzzy control was proposed. On the basis of the combination of the internal model control and the doubleclosedloop control, the fuzzy control was added. The current loop was controlled by internal model PI, and the speed loop was controlled by internal model PI and fuzzy. The experimental results showed that the drive system based on fuzzy internal model control had obvious advantages compared with the traditional doubleclosedloop control system in terms of response speed, overshoot and torque fluctuation.
