T1 - Current-independent torque control of PMSM servo drives N2 - A permanent-magnet synchronous motor (PMSM) is controlled using measurements from a digital, optical incremental encoder. The motor speed is estimated from these measurement. Basic performance results are presented.

T1 - Embedded control of a PMSM servo drive without current measurements N2 - A permanent-magnet synchronous motor (PMSM) servo drive for lightweight robotic platforms that have a high torque demand at low rotational speeds has been developed. First, a current-independent torque controller is derived and cascaded with a speed and position controller, while merely an encoder is used as a sensor device in combination with a speed estimator. Finally, the speed estimator output is compared to gyroscope measurements and the overall functioning is verified on a real system.

ED - Emri, Igor T1 - Current-independent torque control of permanent-magnet synchronous motors N2 - A current-independent torque equation for the permanent-magnet synchronous motor (PMSM) aiming at direct-drive servo applications is derived from a first principles model. Instead of measuring currents, all required control parameters are derived from optical incremental encoder measurements. The results are verified on a real system in test series showing the effect of static friction and proving the obtained torque model.
