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.
