Abstract
To control and stabilize the hydrogen pressure in a multi-stack fuel cell system, a dynamic simulation model of a multi-stack fuel cell hydrogen system structure containing supply and exhaust common rail is built based on Matlab/Simulink. In the control method, the idea of local linearization was adopted. Local linearization models of the system around different steady-state operating points were built and model predictive controller for each interval was designed. This multi-point linearized control model can improve the solution speed and reduce the impact caused by the mismatch problem. The results show that under step operating condition, the deviation of the reactor inlet pressure can be reduced by 22.5%, and the adjustment time can be reduced from 31 to 22 seconds. Under C-WTVC operating condition, power consumption of the blower in the hydrogen system is reduced by 13.6% compared with that of the conventional PID. It is concluded that the controller designed in this paper is better than the traditional PID controller and is more suitable for the hydrogen system of the multi-stack fuel cell.

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
