摘要
Abstract
During the speed sensorless of permanent magnet synchronous motor(PMSM) operating in low speed and near zero velocity, rotor position is hard to estimate using the counter emf. On this basis, reference method of high frequency injection(HFI) is proposed for estimation. On the basis of the motor model, through comparison by two signal injection patterns of the voltage stationary coordinates rotation injected and rotating coordinate d shaft voltage injected, characteristics of two implantation respective are drawn. And we can draw that the speed sensorless current harmonic effect of PMSM exists a periodic interference in the above two ways respectively.关键词
