Abstract
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.
