The operation of a direct torque control (DTC) system for induction motors with the possible presence of unbalanced modes in the motor windings is studied. It is shown that in the presence of asymmetric modes in the motor windings, the classical DTC algorithm becomes unstable. It is proposed to improve the DTC by taking into account the unbalance of the active resistances of the motor stator windings when determining the DTC parameters. This will make it possible to study electrodynamic processes in DTC with the possible presence of asymmetric modes in the windings of induction motor.

“…Therefore, two control methods are most widely used in traction drive systems with induction motors: vector control and DTC. A comparison of the advantages and disadvantages of these control systems is given in works [12][13][14]. The main aspects of the comparison of the two systems are given in the table 1.…”

An analysis of the operating conditions of the traction drives of an electric rolling stock with asynchronous traction motors was conducted. In the process of operation, the electric traction drive with both direct torque control and vector control was found to possibly experience unstable modes, both in terms of power supply and load. The models of electric locomotive traction drives with asynchronous electric motors with either vector or direct torque control were adapted to account for the possible presence of the aforementioned operational factors. As a result of the modeling, the starting characteristics of the electric traction drives with different control systems were obtained both in the absence and in the presence of power supply and load disturbances. The following cases were investigated for the drive with vector and direct torque control in the absence of power supply and torque disturbances: drive output at the rated speed of rotation of the electric motor shaft; 10% reduction in the rated speed; 10% increase in the rated speed. The comparison of the results obtained has demonstrated that, at lower than nominal frequencies, the electric traction drive with direct torque control has higher accuracy in its regulation of the rotational speed and torque, lower power consumption from the power supply, lower torque overshooting, but a higher level of torque pulsations than the electric traction drive with vector control. Meanwhile, at higher than nominal frequencies, the vector control has higher accuracy in its regulation of the speed, lower torque overshooting, shorter duration of transient processes, and lower torque pulsations than the direct torque control. Moreover, as a result of the investigations, the traction drive with direct torque control has been found to be more resistant to power supply and load disturbances. The results of this work are applicable to the investigation of the influence of electric traction drive control methods on the energy efficiency of the traction drive of an electric locomotive with an alternating current (AC).

“…Currently, it constitutes the majority 95% of the energy consumed in industry to provide motive power. Modern drive system technology increasingly demands precise and continuous control of speed, torque and position, while ensuring the highest possible stability, speed and efficiency [1,2]. The direct current motor has satisfied some of these requirements but it is provided with brushes rubbing on the reed collector, which limits the power and the maximum speed and presents maintenance difficulties and operational interruptions [3,4].…”

“…With the progress of power electronics, linked to the appearance of fast switching components, as well as the development of control techniques [7,8], wired or programmed, it is now possible to choose a much more advanced control structure. The FOC of asynchronous and synchronous machines can now highlight control principles making it possible to achieve performance equivalent to that of the DC machine [2].…”

The study presented in this paper consists in the modeling and optimization of the performance of the control of an induction motor (IM) by the application of the sensorless field oriented control (SFOC), using the strategy of the discontinuous pulse width modulation (DPWM) to switch the transistors which form the three-phase voltage source inverter (3Ph_VSI). The latter gives a reduction in the number and the switching losses compared to the space vector modulation (SVPWM). This leads to improve the performance of the IM. The proposed system has many advantages; provides for the decrease in noise, presents an increase in reliability and makes the material less expensive. The study of this control is done in order to show the efficiency and robustness of the method during variations in speed and torque.
