Input Admittance Expressions for Field-Oriented Controlled Salient PMSM Drives
Artikel i vetenskaplig tidskrift, 2012
This paper presents analytical expressions for the converter input admittance in field-oriented controlled permanent-magnet synchronous motor (PMSM) drives. The effect of rotor saliency is taken into consideration and the derived admittance expressions are valid for maximum-torque-per-ampere as well as high-speed (field weakening) operation. Experimental results illustrate the validity of the derived admittance expressions. The presented work can be used to predict dc-link voltage instabilities in PMSM drives in, e.g., railway traction, aerospace and automotive applications.
