暂态控制对于延长固体氧化物燃料电池的使用寿命和扩大其应用具有重要意义。提出了一种基于观测器的暂态控制方法。其基本思想是使用包含在SOFC的稳态不变特性中的估计状态来调节燃料电池电流。其目标是通过控制瞬时燃料利用率，直接解决固体燃料电池中的氢饥饿问题。并对两种不同的SOFC系统进行了验证。跨配置的适用性表明这种方法对于SOFC总体上可能是有效的。控制设计得到了仿真结果的支持。版权所有©2010 by ASME
Transient control is important for prolonging the life of SOFCs and broadening their applications. This paper develops an observer based method for transient control. The essential idea is to regulate the fuel cell current using the estimated state, incorporated within a steady-state invariant property of the SOFC. The objective is to directly address hydrogen starvation in SOFCs through control of transient fuel utilization. The method is demonstrated for two different SOFC systems. The applicability across configurations indicates the possible validity of this approach for SOFCs in general. The control design is supported by simulation results.Copyright © 2010 by ASME
