Vibration Suppression and High Precision Position Control for a Two-Mass Permanent Magnet Synchronous Motor System with Multiple Position Sensor Feedback

For high-precision control of a two-mass system, information of both the drive side and the load side are usually required for obtaining high control bandwidth. However, if the load side position feedback is being used, the mechanical resonance from the mechanical drive components will be inside the position loop. For this situation, the two-mass system will not be stable. In order to maintain the...
