“…Several authors have used the Space Vector Modulation (SVM) technique in controlling the voltage inverter to improve DTC [56][57][58]. The principle of this technique consists in imposing the appropriate vector of tension via a vector modulation of space, in order to proceed to a predictive regulation of the torque and the flux.…”

Conventional direct torque control (DTC) is one of the excellent control strategies available to control the torque of the induction machine (IM). However, the low switching frequency of the DTC causes high ripples in the flux and torque that leads to an acoustic noise which degrades the control performances, especially at low speeds. Many direct torque control techniques were appeared to remedy these problems by focusing specifically on the torque and flux. In this paper, a state of the art review of various modern techniques for improving the performance of DTC control is presented. The objective is to make a critical analysis of these methods in terms of ripples reduction, tracking speed, switching loss, algorithm complexity and parameter sensitivity. Further, it is envisaged that the information presented in this review paper will be a valuable gathering of information for academic and industrial researchers.

“…Their method enables a minimum torque ripple control. They propose a control technique for induction motor in order to obtain a constant switching frequency and hence a torque ripple reduction [12]. In Kaboli and collogues' paper, the effect of flux reference value on the torque ripple of a direct torque controlled induction motor is analyzed.…”

Induction motors are the most widely used motors in industry and home applications due to their robust structure, cheapness, low maintenance and high efficiency. The torque-speed characteristic, which is one of the most critical parameters of induction motors, is highly influenced by rotor slot structures. Therefore, slot type and slot sizing should be performed properly to maximize motor performance during the design process of the induction motor. In the design stage of the induction motor, the choice of rotor slot structure, as well as other parameters are of great importance, while effects such as torque ripple, acoustic noise, and mechanical vibrations should be taken into consideration topics for motor designers. In this study, the effects of torque ripple in induction motors and the changes of torque ripple in different rotor slot structures are investigated. The analyses are performed using the Maxwell RMxprt program. Firstly, static motor models were created and analyzed in the RMxprt program. Afterward, 2-D models of the motors are created and analyzes are carried out to obtain torque ripple changes. 7 different slot geometries are used in the rotor slot structure. Rotor slot geometry with minimum torque ripple and the best performance criteria are determined from the motor models. A 90 kW, 3-phase, squirrel cage induction motor is used as the motor model. According to the obtained results, there was a 31.6% difference between the lowest and the highest torque ripple ratio.

“…For this reason, the sensorless control of a synchronous machine has been an interesting topic. The main idea of this approach is to replace the mechanical sensor by a soft sensor which offers a number of attractive properties one of them being a low cost alternative to hardware speed measurement used in classical motor drives [1][2][3]. For example, the cost of a sensor may exceed the cost of a small motor in some applications.…”
