Electrical Drives Using Model Predictive Controller Strategies

Abstract

High-level control techniques in power gadgets incorporate Predictive controller of current (PC CONTROL) and Predictive controller of torque (PT CONTROL). It is simple to include system restrictions. There is no need for the weighting component. Together with the PT CONTROL and PC controller systems, the SRM method is the most practicable direct control technique since it doesn't require a modulator and offers 10% to 30% more power than an induction motor. With the same current, an induction motor can only generate between 70 and 90 per cent of the force generated by an SRM due to its lagging power factor. When compared to the PT CONTROL and PC controller method employing an induction motor and a 15-level H-bridge multilevel inverter, the SRM approach reduces THD in torque, speed, and stator current by 23 per cent. The transistors are only swapped when necessary to maintain the limits of flux and torque, which minimizes switching losses. To improve the efficiency of a multilevel inverter, semiconductor switches are switched in a specific pattern. In contrast to the PT CONTROL and PC controller approaches using a 2-level voltage source inverter, the fifteen-level H-bridge multilevel inverter employed in this study, coupled with SRM and IM, gives outstanding torque and flux responses and achieves stable and robust operation. This unique strategy quickly caught the interest of academics due to its simple method.
