“…In the literature, several methods have been proposed to reduce or eliminate the chattering phenomenon, which is considered the primary drawback of the classical sliding mode controller [16,17]. However, it is considered that the high-order sliding mode control (HOSMC) is one of the better solutions to reduce chattering and improve resilience during the convergence phase to the sliding surface compared to the conventional sliding mode control [18][19][20]. HOSMC versions use twisting, suboptimal, and STA.…”

In the field of industrial motor control, the inherent design complexity and operational challenge of dual star induction motor (DSIM) have made it a focus of research for many scholars. This study attempts to innovatively propose a refined control approach for DSIM, by deploying two pulse width modulation (PWM) voltage sources combining with indirect field-oriented control (IFOC). Core of our innovation is the integration of a super twisting algorithm (STA) controller, which is a strategy specifically designed to enhance the motor's speed control capability. The paper introduced the technical details of DSIM, with the focus placed on the distinctive configuration of two isolated neutral three-phase windings, set apart by a 30-degree electrical phase shift. Such design has posed certain control challenges, and the STA approach has skillfully addressed these challenges. With the help of Matlab/Simulink simulations, the efficacy of STA controller is evaluated and compared with the common Proportional-Integral (PI) controller, and the simulation results are indicative of the STA controller's superiority, showing a significant improvement in reducing torque ripples and stator current fluctuations. The analysis given in the paper quantifies the improvement, showing substantial reductions in steady-state error and response time, as well as an enhanced disturbance rejection capability. These findings are instrumental in showcasing the STA controller's comparative advantage. Concludingly, the adoption of the STA-based control methodology in DSIM applications not only fosters enhanced speed control and efficiency but also holds the promise of broad applicability across various industrial scenarios. This research, therefore, marks a pivotal advancement in the field of DSIM control, potentially revolutionizing its application in diverse industrial settings. The consistency in the use of professional terminology throughout the paper ensures a coherent and comprehensive understanding of the subject matter.

“…However, the control effectiveness of IFOC for DSIMs faces challenges due to variations in the machine's rotor resistance and other motor parameters [8]. Traditional PI controllers, commonly employed in such scenarios, exhibit weaknesses in rejecting external disturbances and are sensitive to changes in system parameters [8][9][10][11].…”
