As know, Direct Torque Control (DTC) suffers from the high ripples of the torque and flux, caused by the variable switching frequency. Torque ripple in DTC drives can be reduced if an Indirect Three-Level Matrix Converter (ITLMC) is employed instead of a conventional Two-Level Indirect Matrix Converter. Nevertheless, this problem can be still large if low switching frequencies are used. In order to overcome this problem, a Constant Switching Frequency controller (CSFC) is proposed to replace the five-level hysteresis torque comparator for reducing the ripples and improving the flux regulation in low and zero speed operation. Furthermore, the control scheme performance is enhanced by inserting a robust Synergetic Controller (SC) in the outer loop for speed regulation. Simulation results with a comparative analysis have indicated the special merit of the proposed scheme, which makes it competitive with the existing control strategies.

“…Artificial intelligence techniques such as artificial neural networks and fuzzy logic have been studied in many types of research 29,30 However, they usually require powerful microcontrollers in order to rapidly execute their control algorithms. Recently the multilevel inverters were proposed for improved power quality, reduced common‐mode 24,31‐33 . However, these require more number of semiconductor devices, multiple‐input DC voltage steps with the increased levels in the output waveform and the complexity of control.…”
