要約(英語): This paper describes a novel offline parameter identification technique for an interior permanent magnet synchronous motor. In general, the motor controller requires its parameter information to start the motor. Therefore, offline parameter identification is indispensable to avoid degradation in the control performance. The proposed technique changes the configuration of the current regulator and seeks the minimum point of the current norm where the parameter mismatch is eliminated. The unique feature of the method is the use of only the current information and its insensitiveness to the winding resistance variation due to a temperature change. The paper presents an identification process for the q-axis inductance Lq, the winding resistance R, the magnetic flux linkage Ψ and the d-axis inductance Ld. In addition, some simulation and experimental tests are conducted, and their results are presented to demonstrate the validity of the proposed technique. In the final part of the paper, the sensitivity to the winding resistance is also checked by the experimental test.
