摘要：
A rotor position sensorless control system of a permanent magnet synchronous motor has been used widely for practical use in home electronics as well as in the industry. Recently, higher performance sensorless control has been required to expand its applicability in various fields. Accurate estimation of the rotor position at a standstill or an initial rotor position is important to achieve sensorless control over the entire speed range. This paper proposes a new method of the rotor position estimation of an interior permanent magnet synchronous motor based on a model reference adaptive system (MRAS) at a standstill. The proposed method estimates the rotor position by injecting a high-frequency pulse voltage. Several experimental results are presented to show the performance of the method. © 2012 The Institute of Electrical Engineers of Japan.
