Abstract
The integration of renewable energy sources in industrial systems has led to a rising demand for DC motor drives, primarily due to their precise speed control capabilities. Although DC motors typically require more maintenance than their AC counterparts, their responsiveness makes them suitable for dynamic control applications. This study explores a speed regulation method for a current-controlled DC motor using a Fractional-Order PID (FOPID) controller, with parameter optimization guided by the Model Reference Adaptive Control (MRAC) approach based on the MIT rule. The motor system is modeled mathematically and implemented in MATLAB/Simulink to simulate both standard FOPID) and MRAC-tuned FOPID control strategies. The controller parameters are adaptively adjusted to minimize a defined performance criterion. The performance of both controllers is analyzed using key time-domain metrics—such as rise time, settling time, overshoot, and steady-state error. Simulation results confirm that the MRAC-based FOPID controller delivers superior dynamic performance, highlighting its potential for robust and efficient speed control in adaptive DC motor drive systems.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
