要約(英語): This paper proposes a new approach to achieve online identification of the q-axis inductance of the interior permanent magnet synchronous motor (IPMSM) based on the relationship between the mismatch of Lq and the d-axis feedback current. The value of the d-axis feedback current depends on the mismatch of Lq, and the consecutive samplings of the d-axis feedback current make it possible to calculate the true value of Lq. The proposed identification technique has been examined through some experimental tests. The test results demonstrate the fast convergence of the identified Lq to the true one with a small error.
