| Electrical machines are widely used in many areas today. Regardless of the application, the most efficient electrical machine production and the most efficient driving techniques are tried to be developed for energy efficiency. Therefore, permanent magnet synchronous machines (PMSM) have been widely used in industry, electric vehicles and elevator applications, which are frequently used in daily life, in recent years (Ding, Hou, & Wang, 2022; Polat, Akyun, & Nory, 2022; Zhang, Zhao, Dai, & Li, 2022). Even though PMSMs are preferred due to their excellent features such as high-power density, high efficiency and low acoustic noise, it is possible to benefit more from their efficiency by using efficient driving techniques.The techniques used in the control of PMSMs can be broadly categorized into two as field-oriented control (FOC)(Nicola & Nicola, 2022; Zhao, An, Chen, Cao, & Li, 2022) and direct torque control (DTC)(Petkar & Thippiripati, 2022; Qiu et al., 2022). In both techniques, a closed-loop control system is created and the error is minimized with the help of controllers by comparing thecontrol variables measured from the machine with reference values. While control variables are dq-axes current for FOC technique, they are torque and stator flux vector for DTC. Therefore, the name of the technique is direct torque control technique. |
