Abstract: Permanent magnet synchronous motor (PMSM) vector control system has fast response speed, small overshoot, small torque ripple, wide speed range, small size and other characteristics, has a good dynamic and static performance. In this paper, a PMSM vector control servo system with the core of DSP was constructed, and presented its hardware and software processes. The test showed that the system has good control performance.
