通过将被动辐射制冷策略与个人热管理技术相结合,为缓解人体在户外活动中的热不适感提供了新的思路。然而,目前大多数被动辐射制冷材料在穿着舒适性和耐用性方面存在不足。本文采用微阵列技术,成功制备出了具有辐射制冷能力的定制光子工程可穿戴纺织品。所开发的辐射制冷纺织品(RCTs)具有一定的透气透湿性、结构稳定性和扩展光谱响应性(太阳光反射率91.7%、大气窗口发射率95.8%)。在正午炎热环境的室外降温测试中,RCTs所覆盖的皮肤模拟器温度比棉织物低4.4 ℃。这种仿生结构的开发为可穿戴、热湿舒适和结构稳定的辐射制冷纺织品在个人热管理领域的应用提供了新的见解。

为了让人体感到热舒适,同时节约能源,个人热管理正逐渐成为一种颇有前景的策略。通过更好地控制人体散热,个人热管理可以实现有效的个人降温和保暖。本文提出了一种简单的表面改性方法,在商用织物的基础上定制热传导和热辐射特性,以便更好地管理从人体到环境的整个传热路径。本文对一种同时具有降温和保暖效果的双功能非对称织物(BAF)进行论证。凭借粗糙度不对称和表面改性等优点,BAF在降温模式下通过增强热传导和热辐射表现出显著的降温效果;在保暖模式下,两条路径的散热都减少,从而实现个人保暖。结果表明,在BAF的降温和保暖模式下测得的皮肤温差可达4.6 ℃,表明一件BAF衣服可以扩大人体的热舒适区。希望本研究可为用于个人热管理的织物的设计提供新的视角,并为现有的用于个人降温和保暖的织物的简单改性提供新的解决方案。

Power maximization has always been a practical consideration in wind turbines. The question of how to address optimal power capture, especially when the system dynamics are nonlinear and the actuators are subject to unknown faults, is significant. This paper studies the control methodology for variable-speed variable-pitch wind turbines including the effects of uncertain nonlinear dynamics, system fault uncertainties, and unknown external disturbances. The nonlinear model of the wind turbine is presented, and the problem of maximizing extracted energy is formulated by designing the optimal desired states. With the known system, a model-based nonlinear controller is designed; then, to handle uncertainties, the unknown nonlinearities of the wind turbine are estimated by utilizing radial basis function neural networks. The adaptive neural fault tolerant control is designed passively to be robust on model uncertainties, disturbances including wind speed and model noises, and completely unknown actuator faults including generator torque and pitch actuator torque. The Lyapunov direct method is employed to prove that the closed-loop system is uniformly bounded. Simulation studies are performed to verify the effectiveness of the proposed method.
