REACTIVE COMPRESSOR SURGE MITIGATION STRATEGY FOR A FUEL CELL POWER SYSTEM |
摘要 |
Systems and methods to mitigate surge conditions in a compressor of a vehicle fuel cell system. A first surge mitigation strategy regulates a cathode backpressure valve, if the compressor is operating at or above a threshold speed. A second surge mitigation strategy regulates a recirculation valve if the compressor is operating below the threshold speed. In one form, a feedback-based control may be used as part of a larger feedforward-based control strategy such that the mitigation is part of a reactive control strategy. The strategy may additionally be implemented in a processor-based controller. |
