Abstract
This paper proposes an enhanced Nonlinear Model Predictive Control (NMPC) framework that incorporates a robust, convergent variant of the resilient propagation (RPROP) algorithm to efficiently solve the Nonlinear Optimization Problem (NOP) in real time. The controller is developed for both constrained and unconstrained trajectory tracking of Wheeled Mobile Robots (WMRs), with operational constraints handled via the external penalty method. The proposed method introduces adaptive step sizes and a backtracking mechanism, significantly improving convergence speed without compromising accuracy. Simulation results show that, even under constraints, the proposed method reduces computational time by a factor of 6 to 11 compared to the Interior Point method and 2 to 4 compared to the Active Set method. In addition, it achieves superior tracking accuracy, with root mean square (RMS) position tracking errors reduced by approximately 50% relative to the benchmark methods. Real-time experiments conducted on the Robotino Festo Omnidirectional Mobile Robot (OMR) validate the method’s practical effectiveness, demonstrating faster convergence and improved velocity tracking performance, while maintaining comparable or better position tracking. These findings establish the proposed controller as a computationally efficient and accurate solution for real-time WMR trajectory tracking.

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
