Abstract

This paper provides analysis result about effects of parameter variation on mono inverter dual parallel (MIDP) surface mounted permanent magnet synchronous machine (SPMSM) drive system. Parameter variation is natural phenomenon in real system and is caused by manufacturing tolerance, temperature variation, and magnetic saturation. In the MIDP motor drive system, parameter error can be occurs not only in common but also in individual. Especially, effects of parameter difference between the motors should be considered because it can affect not only efficiency but also stability. In this paper, the effects of common and individual parameter variation on MIDP SPMSM drive system is analyzed and simulated.
