Abstract

This paper proposes a coordinated control strategy for the cathode pressure and the supply manifold pressure in proton exchange membrane fuel cell (PEMFC) air supply system based on a triple-step method. First, a Luenberger observer is designed to estimate the unmeasured cathode pressure in real-time. To facilitate nonlinear controller design, specific affine-like, second-order input-output models are derived for cathode pressure and supply manifold pressure, incorporating estimation and compensation of modeling uncertainties using two extended state observers (ESOs). Next, two tracking controllers are designed based on the triple-step method to regulate cathode pressure and supply manifold pressure towards their desired setpoints, ensuring closed-loop stability through Lyapunov-based methods. Finally, the effectiveness and advantages of the proposed nonlinear triple-step controllers for the air supply system are validated.
