度低、不受限於特定馬達結構且確保啟動成功。摘要(英) This thesis discusses the current amplitude close loop I-f startup combined with
improved pulse voltage injection method to complete the permanent magnet synchronous motor startup process without position sensors. In the I-f startup method, a
specific vector command is given in a pre-positioning manner, which will cause the
reversal and shake of the motor during the startup process. Therefore, this thesis estimates the initial rotor position according to the characteristic of the equivalent inductance value due to the different rotor position. Additionally, the motor model
equivalent mathematical model is used to control the internal reaction virtual power
to maintain the startup process satisfying the FOC(?? = 0) characteristics.
This startup method reduces the system cost caused by the use of position sensors
to measure the rotor position signal in the PMSM control method. Compared with
other sensorless startup strategies, the algorithm has low complexity, it is not limited
to a specific motor structure and ensures successful startup關鍵字(中) ★ 永磁同步馬達
