| 英文摘要 |
| The net power of the proton exchange membrane fuel cell (PEMFC) system can be effectively improved by
adjusting the oxygen excess ratio (OER) to a desired range. To this end, the dynamic model of the PEMFC air supply
system is transformed into a normal form in this paper, and the stability of the internal dynamics is analyzed. Then,
based on the extended state space equation, a novel adaptive high–order sliding mode method is proposed, which could
not require the knowledge of accurate PEMFC air supply system model and the bounds of the uncertainties/perturbations.
Moreover, the control gain obtained from the developed adaptive scheme ensures the tracking errors convergence to a
defined neighborhood of zero. Finally, the convergence and stability of the system are verified by Lyapunov theory analysis.
Meanwhile, the adaptability and superiority of the proposed controller are indicated by the results gained from numerical
simulations and hardware-in-the-loop (HIL) experiments. |
