“…Direct torque control (DTC) aims to control directly the stator flux and the torque by selecting the appropriate inverter state. DTCs can be classified into three categories: switching-table based DTC (ST-DTC) [85][86][87][88][89][90][91][92][93][94][95], the duty-ratio-based ST-DTC (D-DTC) [96,97] and space vector modulation DTC (SVM-DTC) [98,99].…”

“…Hence, the duty-ratio-based ST-DTC (which divides one sampling period into two intervals and applies active vectors and zero vectors together) was adapted to DTP machines in [96] and obtained the reduction of torque ripples, but it still suffered from drawbacks, such as its variable switching frequency [97]. Therefore, SVM-DTC, presented in Figure 23, was adapted to DTP drives to deal with the torque and flux ripple as well as the variable switching frequency.…”

“…The value θ s represents the electrical rotor angle. In this way, the flux and torque ripples can be reduced significantly, and constant switching frequency can be achieved, but this method features the disadvantage of a deteriorating dynamic response, as analyzed in [96,97].…”

Multiphase electrical machines are advantageous for many industrial applications that require a high power rating, smooth torque, power/torque sharing capability, and fault-tolerant capability, compared with conventional single three-phase electrical machines. Consequently, a significant number of studies of multiphase machines has been published in recent years. This paper presents an overview of the recent advances in multiphase permanent magnet synchronous machines (PMSMs) and drive control techniques, with a focus on dual-three-phase PMSMs. It includes an extensive overview of the machine topologies, as well as their modelling methods, pulse-width-modulation techniques, field-oriented control, direct torque control, model predictive control, sensorless control, and fault-tolerant control, together with the newest control strategies for suppressing current harmonics and torque ripples, as well as carrier phase shift techniques, all with worked examples.

<span>Multilevel inverter (MLI) is commonly utilized in direct torque control (DTC) for medium and high power applications. The additional voltage vectors generated by MLI can be manipulated to achieve the optimal selection for the inverter switching states in the DTC control systems. Previously, a review of DTC which focused more on the two-level inverter for induction motor as well as a review of the multilevel converter in industrial applications had been implemented individually. However, a review on DTC development in MLI was insufficient in both papers. Therefore, this paper aims to give a comprehensive review of the improvement of DTC via various MLI applications. It is reviewed according to the applicable multilevel inverter topologies in the DTC system. The comparison of DTC by using conventional and multilevel inverter is synthesized. Thus, this review paper will hopefully lead researchers in further research activities actively.</span>

“…Otherwise, the excessive of PI error slope consequences to the large torque ripple in DTC. Duty cycle-based strategy is another typical approach to improve the performance of DTC as proposed in [21,27,28]. It enables to manipulate the voltage vectors within their stipulated time in each interval switching that directly able to control the torque slope profile.…”

<span>In this paper, the improvement of torque ripple reduction will be focused based on the optimal voltage vector. This is attained by using five-level CHB inverter that applies in DTC drive control as a proposed method. The analysis is performed and simulated by using MATLAB/Simulink. In order to support the analysis, the comparison is realized between proposed method and conventional method which it applies two-level inverter. It will be analysed at constant torque region or steady-state operation on different range of operating speed which the speed is controlled by adjusting the motor load. Meaning that, the speed controller is neglected during analysis. Nevertheless, the adjustment of motor load must be applicable to the optimal voltage vector. The look-up table of five-level CHB inverter will become a guideline to select the optimal voltage vector. Therefore, it can maintain the simple structure of DTC hysteresis-based that fed by using five-level CHB inverter. As a result, the torque ripple can be minimized and torque capability can be retained even at low operating speed compared to the conventional DTC.</span>
