On the basis of that, the stator q-axis high-frequency voltage injection was and motor＇ s high-frequency induction current was used to identify the rotor position angle. A specific frequency notch filter and high cut-off frequency low-pass filter were designed for the harmonic content distribution characteristics of rotor current supplied with thyristor controlled rectifier, to realize rapid extraction of rotor~ effective high-frequency current. The rotor position and speed information was obtained by using SPLL to realize wide |
