Parameter Identification Techniques for PMSM: An Overview

In hybrid and electric vehicles, the stable and precise operation of the motor significantly impacts vehicle performance. The operation of a motor depends on its electrical and mechanical parameters. This paper focuses on PMSM motor electrical parameters such as stator resistance, d-q axis inductance, and permanent magnet flux linkage. Identifying the electrical parameters of a PMSM motor is complex due to the non-linear relationship between input and output. A change in one parameter can alter the dynamic response of motor. This paper presents a comparative analysis of various PMSM electrical parameters identification techniques.
