METHOD FOR CONTROLLING AIR FLOW IN A FUEL CELL POWER SYSTEM

摘要

One aspect of the present disclosure is directed to a fuel cell power system. The system may include one or more fuel cells configured to generate electric power and a compressor configured to supply compressed air to the one or more fuel cells. The system may further include one or more sensors. The sensors may be configured to generate a signal indicative of at least one measured parameter of air flow across the one or more fuel cells. The system may also include a controller in communication with the one or more fuel cells, the compressor, and the sensors. The controller may be configured to determine a desired pressure drop 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 and a feed forward gain parameter.

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 generate a signal indicative of at least one measured parameter of air flow 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; andadjust the control command based on a feedback gain parameter and a feed forward gain parameter.
