基于飞机快速、高效除冰的目的,设计与制备低冰粘附力的涂层,以期实现较低(甚至超低)的冰层粘附强度,减轻对现有高能耗主动防/除冰技术的依赖程度。总结了现有疏冰涂层的发展历程,基于不同涂层的防覆冰机理,以冰粘附性能或除冰外力作为主要技术指标来评估涂层的防/除冰性能,依次阐明了超疏水涂层、超润滑涂层和低界面韧性涂层的除冰机理,具体介绍了三者的疏水/冰效果,对比分析了各自的优劣性。其中重点阐述了低界面韧性涂层大面积除冰的优势,即在大面积结冰条件下,以冰层剪切粘附强度定义的(超)疏冰涂层材料,其除冰外力都受限于结冰
为了满足直流负载电压的稳定性及固体氧化物燃料电池(SOFC)的耐用性和安全性的要求,设计了两个控制回路分别对SOFC的输出电压和燃料利用率进行控制。通过设计一个简单的控制回路来使燃料利用率保持在恒定值,并在此基础上开发了一个非线性模型预测控制器以控制SOFC的输出电压。该非线性模型预测控制器基于改进的支持向量机(SVM)预测模型,首先利用Lipschitz quotients准则确定SVM预测模型的结构,然后通过人工蜂群算法(ABC)优化SVM参数。仿真结果表明,所提的基于ABC-SVM模型的SOFC预测
