1. A fuel cell power system comprising:
one or more fuel cells configured to generate electric power;
a compressor configured to supply compressed air to the one or more fuel cells;
one or more sensors associated with the one or more fuel cells and configured to (i) measure pressure of the compressed air at a cathode input of the one or more fuel cells, (ii) measure pressure of the compressed air at a cathode output of the one or more fuel cells, (iii) determine a measured pressure drop in air flowing across the one or more fuel cells based on a difference between the pressure at the cathode input of the one or more fuel cells and the cathode output of the one or more fuel cells, and (iv) generate a signal indicative of at least one measured parameter of the measured pressure drop across the one or more fuel cells; and
a controller in communication with the one or more fuel cells, the compressor, and the one or more sensors, the controller being configured to:
determine a desired pressure drop across the one or more fuel cells based on at least one calculated parameter;
determine a control command for the compressor based on the desired pressure drop; and
adjust the control command based on a feedback gain parameter, wherein the controller is further configured to determine the feedback gain parameter based on a difference between the measured pressure drop and the desired pressure drop.
