固体氧化物燃料电池因其燃料的灵活性和高效率而成为极具吸引力的能量转换装置。燃料利用率是SOFC系统中的一个关键变量，它直接影响效率和寿命。在这篇文章中，我们提出了一种控制策略，以缓解在负载瞬变期间燃料利用率的剧烈波动。该策略采用了一种基于反馈的动态输入整形方法。从基于模型的分析中得出的初步控制律构成了本设计的基础。该策略需要集成燃料处理器上游的一个燃料流量传感器，并允许方便地集成到综合混合燃料电池控制算法中。
Solid Oxide Fuel Cells are attractive energy conversion devices due to their fuel flexibility and high efficiency. Fuel utilization is a critical variable in SOFC systems that directly impacts efficiency and longevity. In this paper we propose a control strategy for mitigating drastic fluctuations in fuel utilization that arise during load transients. The strategy uses a feedback based dynamic input shaping approach. A preliminary control law derived from a model-based analysis forms the basis of this design. The strategy requires one fuel flow sensor upstream of the integrated fuel processor and admits convenient integration into a comprehensive hybrid fuel cell control algorithm.
