Adaptive State Estimation Algorithm for Sensorless Vector Control of Permanent Magnet Synchronous Motors at Medium and High Speeds under Parametric Uncertainty
An adaptive estimation algorithm is proposed to improve the accuracy of rotor speed and position determination for a permanent magnet synchronous motor (PMSM) in a sensorless control system, without requiring prior knowledge of the exact motor parameters. The method is developed to eliminate the shortcomings of convent...
