A Review of State-of-the-art Techniques for PMSM Parameter Identification

In this paper, a review of previous research in d- and q-axis inductance identification techniques for permanent magnet synchronous motor (PMSM) is presented. The d- and q-axis inductances have an important influence on both the transient and steady-state responses of PMSM. Therefore, their accurate information is essential not only for predicting the responses but also for designing system controllers. However, standardized procedures for the PMSM inductance identification have not yet been established. The main purpose of this paper is to provide an understanding of the various parameter identification methods. Conventional techniques are reviewed and introduced with their inherent advantages and drawbacks.
