Abstract:
A position observer for control-based torque ripple mitigation in permanent magnet synchronous machines (PMSMs). Rotor position is determined using data from two sources: a piezoelectric sensor for initial position and low-speed detection, and a single Hall-effect sensor for high-speed detection.
