Abstract

fetched live from OpenAlex

The transportation sector is widely acknowledged for contributing the largest share of greenhouse gas (GHG) emissions. This study presents a strategy aimed at enhancing energy efficiency in electric vehicles by employing an easy dynamic direct voltage method without current sensing for MTPA speed control of interior PMSMs. The approach involves following the MTPA angle using a distinctive voltage magnitude, eliminating the need for current sensing at any speed in electric vehicles. This results in minimized current and power consumption, ultimately leading to heightened energy efficiency. The accomplishment of these objectives is facilitated by incorporating the motor’s dynamic model, which enhances controller responsiveness, especially during dynamics. The experimental outcomes, along with energy consumption measurements and an energy efficiency analysis, substantiate that the suggested Easy Dynamic Direct Voltage Control (E-DDVC) technique is a promising alternative to current MTPA methodologies in interior-PMSM drives. This strategy demonstrates the ability to maintain high energy efficiency, particularly during dynamic operations.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
