| 英文摘要 |
| Mathematical model of surface mounted permanent magnet synchronous motor considering the harmonic component of permanent
magnet flux and stator inductance is established, then it is simplified. Based on the theoretical analysis method,
three-phase back EMF measurement is analyzed by FFT, and the harmonic component of three-phase EMF is obtained.
Then it is used to calculate the sixth and twelfth harmonic component of rotor flux on dq axis. On this basis, a state
observer based on Lyapunov stability theory is designed to identify the sixth harmonics of stator self inductance and mutual
inductance on dq axis. Experimental results verify the effectiveness and practicability of the harmonic parameters
identification algorithm in this paper. |
