Mathematical Modelling of Permanent Magnet Synchronous Motor with Rotor Frame of Reference

Abstract

The mathematical model of PMSM, using the powerful
simulation modeling capabilities of Matlab/Simulink is
implemented. The main advantage of SIMULINK over other
programming softwares is that, instead of compilation of
program code, the simulation model is built up systematically by
means of basic function blocks. With the simulation of the motor,
we can analyse a variety of simulation waveforms and it provide
an effective means for the analysis and design of the PMSM
control system. PMSM has more advantages like compact form
with high torque density and less weight, higher continuous
torque over a wider range of speeds, lower rotor inertia, higher
dynamic performance under load, higher operational efficiencies
with no magnetizing current, and the corresponding absence of
heat due to current in the rotor, low torque ripple effect, more
robust performance compared to dc motors, because of these
advantages Permanent magnet synchronous motors are
increasing applied in several areas such as traction, automobiles,
robotics and aerospace technology. In this paper mathematical
modeling of PMSM is done and simulation results compared
with MATLAB SIMULINK model.
