It is well known that the control problem of the double pendulum on a cart（DPC） system is challenging since it is a complicated underactuated mechanical system with high nonlinearity. This paper first studies a swing-up and tracking control problem of the DPC system with time-varying reference signal. A novel switched swing-up and tracking controller is proposed,which can be carried out in two steps. In step one, the energy-based swing-up controller is used to drive the double pendulum to the neighborhood of the up-up equilibrium point. In step two, based on approximate nonlinear output regulation theory, the polynomial approximation based tracking controller is used to achieve high precision position tracking control. Finally, the simulation results illustrate the effectiveness of our design.

高压燃气储罐泄漏极易诱发喷射火。通过搭建储罐壁面限制条件下不同喷射角度的喷射火实验装置,对近喷口流场受限的喷射火进行了系统研究,并验证了装置测试的可重复性。实验结果表明,储罐壁面限制条件下推举高度小于自由射流的推举高度,并通过数值模拟分析了两种空间条件下空气卷吸流场的差异性,从而物理解释了储罐壁面限制条件对推举高度的影响。两种空间条件下火焰长度都随喷射角度的增加而减小,但自由垂直射流的火焰长度小于储罐壁面限制条件下的火焰长度。火焰行为由浮力控制转为动量控制的临界Froude数与喷射角度和空间限制条件无关。研究还发现,与自由射流相比,储罐壁面的阻塞效应会降低火焰的推举速度,提高火焰的吹熄速度。

通过搭建坑道限制条件下小尺寸喷射火实验装置,模拟研究埋地管道泄漏场景中引发的水平喷射火火焰特性。火焰受坑道侧壁的限制,先撞击坑道而后沿着侧壁向上发展形成垂直火焰。实验结果表明,随着泄漏质量流量的增加,火焰长度先增加后减小,而火焰宽度不断增加。同时发现,在一定条件下火焰两侧会出现涡旋对,形成一对反向旋转的火焰,为了探究其形成原因及产生条件,结合数值模拟手段进一步研究了火焰流场不稳定性。

Recent development in electrode design for wide-temperature supercapacitors

引用

Science China Chemistry 2025年第1期68卷 96-117页

作者： Jianhong Liu Qiang zhou Yuxiao Lin Xinsheng Zhao Guangmin zhou Xiaoxiao Li School of Physics and Electronic Engineering Jiangsu Normal University Tsinghua-Berkeley Shenzhen Institute & Tsinghua Shenzhen International Graduate School Tsinghua University

An ever-increasing market demand has stimulated the soaring enthusiasm of researchers to develop wide-temperature supercapacitors(SCs). The active electrode is one of the most important parts of SC, which is directly related to the energy density,power transmission and long-term cyclability of the device in the wide-temperature environment. Compared with the SC electrodes aimed for room-temperature application, the SC electrodes for operating at wide-temperature scene often face greater challenges. In this review, the main challenges of SC electrodes under various temperature conditions, including low, high and cross-fade temperatures, are summarized. The relevant performance decay and failure mechanisms of wide-temperature SC electrodes are analyzed. In addition, this review deals with the recent studies and developments in robust wide-temperature SC electrodes with respect to the rational design of electrode structures and the exploitation of advanced active materials. Finally, the future directions for exploring reliable wide-temperature SCs are also proposed.
