A model predictive control scheme with torque ripple mitigation for permanent magnet motors


S. Mariéthoz

IEEE IECON, Industrial Electronics Conf., Porto, Portugal

This paper analyses the effect of torque ripple on back-EMF based speed observers for permanent magnet motors. It introduces a scheme that allows to improve these estimates and to identify the motor inherent torque ripple. A high-dynamic performance sensorless model predictive controller is proposed to effectively mitigate selected torque harmonics. The presented concepts are validated experimentally.
