Position Sensorless Field Oriented Control of IPMSM Under Parameter Uncertainties

Abstract

Abstract Permanent magnet synchronous motors (PMSMs) are widely used in industry due to their high torque per volume ratio, low noise, efficiency and wide stable operation region. Especially in home appliance applications, obtaining high torque using small motors and low audible noise has crucial importance. Therefore, conventional DC motors have been replaced by the permanent magnet synchronous motors in the modern applications. In this study, field oriented sensorless control over wide speed range is carried out under parametric uncertainties. The pole coloring concept is used for the control of a PMSM in an industrial setup for the first time. The design method and experimental results are presented.
