Utility of Field Weakening and Field-Oriented Control in Permanent-Magnet Synchronous Motors: A Case Study
Engineering Proceedings(2023)
Abstract
The significance of electric vehicles is progressively escalating, underscoring the criticality of technologies underpinning the functionality of their propulsion systems. This particular case study delves into the simulation of field-oriented control, coupled with field weakening, aimed at regulating a salient-pole permanent-magnet synchronous motor (PMSM). This approach involves the utilization of two cascaded loops for current and voltage, each employing PI controllers. The fine-tuning of these controllers’ parameters hinges on the motor characteristics, as well as the desired response bandwidth.
