“…The research scholars in [51] present a conventional DTC control mechanism which also includes optimization of the voltage vectors through a torque minimization strategy, while the authors in [52] present a discrete duty-cyclecontrol method for DTC which incorporates a model predictive solution. While the work present in [50] does present convincing results, with a very simplified control technique, the authors do not provide a comparison between the proposed technique and DTC-SVM-TC that does not contain the optimization strategy employed (such as making use of the symmetrical SVM technique). Such a comparison would be useful as it would allow the reader to gauge the improvement that fundamental voltage vector duty ratio optimization provides to the system.…”

“…Furthermore, the authors in [50] present a study of DTC for induction motors which is based on minimum voltage vector error. The control mechanism proposed also utilizes DTC-SVM-TC; however, the duty ratio of the fundamental voltage vector is optimized in order to minimize the error that occurs between the reference voltage vector, and the voltage vector that is finally imposed.…”

Transport and vehicular travel are essential for socio-economic growth, as they enable the operation of cities and businesses globally. However, large percentages of the transport sector currently rely on internal combustion engine vehicles, causing an increase in greenhouse gases and air pollution. Electric vehicles provide a promising solution to the issues faced by the transport sector. As a result, optimization of the electric vehicle powertrain is a key area, with the traction motor control mechanism forming a major component of the powertrain. Consequently, this paper aims to review the novel control techniques which have been applied to the traction motor system in electric vehicles. Direct torque control and indirect field oriented control are commonly applied control techniques as they allow for advanced control of the induction and permanent magnet synchronous motors currently used in most of the electric vehicles being produced. In general, various improvements have been made to conventional direct torque control and indirect field oriented control schemes, in order to reduce ripple and improve parameter insensitivity. While efforts are still being carried out in these areas for electric vehicle applications, it was found that there has been a large emphasis placed on powertrain efficiency improvement through optimization of the traction motor control system. Efficiency improvements have recently been achieved through optimal selection of stator flux and DC link voltage values. Research into efficiency improvement is likely to continue as extended vehicle range can be achieved.

“…The voltage selection for CDTC and TCSF-DTC is executed in such a way that the applied voltage gives a fast response in monitoring flux and torque. According to the work stated in (6) , for the n sector, a vector Vn+1 is used to increase both flux and torque. In contrast, Vn+5 is applied to decrease torque and increase flux.…”

Objective: It is recommended to use DTC when a quick response time is required. However, the ripple in torque, as well as flux, is the biggest drawback of DTC. This study presents a comparative analysis of two direct torque control methods CDTC and TCSF-DTC for PMSM's that operate at a constant speed. Method: Matlab 2021b is used to model both CDTC and TCSF-DTC including all switching signals generation. During the simulation, the switching state is chosen to achieve a fast torque and flux response. Finding: A comparison of the two methods was made based on the results of the simulation. In comparison to CDTC, TCSF-DTC uses double-tracking control to manipulate flux values, which minimizes flux ripples. Although the torque performance is similar in both cases, TCSF-DTC has better flux ripple minimization. In both cases, the torque ripple is 2.857%, whereas the flux ripple is 1.879% and 0.1% for CDTC and TCSF-DTC respectively Furthermore, the simulation result for the supply voltage of the motor illustrates improvements in the harmonic distortion and fundamental component magnitudes. Novelty: Flux and torque are controlled independently in DTC, but a PI controller is added for TCSF-DTC. This study compares the performance of CDTC and TCSF-DTC for flux and torque ripple at a constant speed to recommend the control scheme that is suitable for fine torque and flux ripple control. It has been raised in several works that DTC ripples can be reduced, and researchers have recommended several DTC algorithms, including model-predictive DTC, space vector pulse width modulated DTC, and duty ratio optimization. As a result of adding this feature, computational complexity increases. In particular, duty ratio optimization increases computation complexity for slope estimation. The main advantage of this scheme is that it does not increase the complexity of signal processing but it is effective in minimizing flux ripple.

“…The use of direct controllers such as Finite-Control-Set Model-Predictive Controllers (FCS-MPC) [1], Direct Power Controllers (DPC) [2], Direct Torque Controllers (DTC) [3], and Finite-Control-Set Noise-Shaping Controllers (FCS-NS) [4] has been facilitated by the increasing computational power and availability of embedded microcontrollers. The operation of direct controllers consists in selecting a switching state of the converter for each sampling period.…”
