摘要：
Position sensorless vector control of interior permanent magnet synchronous motors (IPMSMs) has been used for downsizing, cost reduction, and high reliability. In the position sensorless vector control, the q-axis inductance decreases as the q-axis current increases due to the load variation, which results in deterioration of the position estimation performance without considering the q-axis inductance. Here, the authors propose an innovative adaptive estimation based on the dynamic certainty equivalence principle for high-performance position sensorless control for IPMSMs. The effectiveness of the proposed adaptive scheme is verified through experiments.
