This paper presents a torque ripple reduction method of permanent magnet synchronous motors (PMSM) driven by an indirect matrix
converter (IMC) based on torque predictive
control. The indirect matrix converter guarantees a sinusoidal waveform of the
input–output
currents and high-power density. In
addition, this architecture does not have large capacitors in the DC-link. As
the indirect matrix
converter has these advantages, it is
used in various applications such as in railway cars and electric vehicles.
Currently, various torque
control methods for permanent magnet
synchronous motor drives using indirect matrix converters are being actively
studied. In this
paper, a torque ripple reduction method
of permanent magnet synchronous motor driven by an indirect matrix converter
based on
torque predictive control is proposed.
The improved torque predictive control method can decrease the ripple of the
output current
and torque in the low- and high-speed
load ranges. In addition, this method is able to enhance the dynamic torque
response relative
to using the conventional torque
predictive control. The effectiveness of the proposed control method is
verified via simulation and
experimental results.
