| Abstract |
Position information is very important when driving the Permanent Magnet Synchronous Motor(PMSM). Generally, resolver is used to obtain exact position information. However, it generates periodic position errors due to the transformer ratio difference and excitation signal distortion. When the vector control is done with the position information that includes position error, torque ripple is generated from time to time.This paper proposes the solution through analysis of above problem. Also, it’s validity is verified by simulation and experiment. |
