摘要：产品设计师为产品赋予一定的外在形式,并指明了它的功能性,也向消费者传递出一定的情感信息。产品设计的目的是为了满足人们在生活中的特定需要,而这种需要不仅仅体现在产品对于消费者所能实现的物质功能方面,同时也体现在精神生活方面。随着趣味性产品的出现,现代人更注重的是极富个性和创意的个人主义情感。创意、个性、大胆和热情,将注定作为新时代的一部分设计元素不断发展。重视消费者的情感需求,将是设计千古不变的一个基本原则。

摘要：研究囚徒困境中促进合作演化的控制设计及控制下的合作演化路径问题.基于标签捐赠机制,设计对个体贴标签的规则,增加个体的认知能力,协助个体决策.建立反馈控制下的合作演化动态模型,分析贴标签控制促进合作演化的实现途径,论证容许控制上界与控制效果之间的一致性.通过基于合作识别和基于背叛识别两种控制的比较,得到两个结论.一是合作率较低时,基于背叛识别的控制更容易促进合作率提升,反之,基于合作识别的控制则更容易实现.二是这两种识别方式需要相同的博弈重复次数.仿真分析各参数和控制上界对控制律设计和合作演化轨迹的影响.

摘要：变循环发动机(VCE)具有较多的可调参数,为了进行变循环发动机的多变量稳态控制规律优化设计,提出了用于变循环发动机稳态控制规律优化设计的一种新方法-逆算法。该方法基于敏感性系数矩阵,采用可调参数替换传统部件级性能计算模型中的独立变量,在给定变循环发动机主要状态参数和部件参数的条件下,实现了可调参数的求解,进一步完成发动机稳态控制规律的优化设计。对比表明,逆算法的计算精度和收敛速度与传统算法一致,收敛性得到了改善。对带有核心机驱动风扇(CDFS)的双外涵变循环发动机亚声速巡航的节流状态控制规律优化后,使得巡航推力下的安装耗油率比定几何的双外涵和单外涵发动机分别下降7.8%和16.4%,而地面安装耗油率最大降低约3.4%。结果表明,逆算法是变循环发动机稳态控制规律优化设计的一种有效途径。
