摘要：This paper presents a novel observer-based control scheme for discrete-time piecewise affine systems based on a piecewise-quadratic Lyapunov function. The key issue addressed in this paper is that the currently active region of the system is unknown, and can not be inferred from the measured *** approximating polytopic operating regions by ellipsoids and using the singular value decomposition technique to treat the constraint of matrix equality, the suggested control method can be formulated as linear matrix inequalities (LMIs), and solved much more efficiently than existing methods which could be only cast as bilinear matrix inequalities. A numerical example is also given to verify the proposed approach.

摘要：锂金属电池被认为是最有前景的下一代储能设备之一,但是锂金属电池的安全性问题以及锂枝晶生长问题严重阻碍了它的实用化进程.固态电解质可以有效解决这一安全性问题,表现出能够抑制锂枝晶生长的巨大潜力,并因此受到大家的关注.其中聚环氧乙烷(PEO)基固态电解质由于具有较高的安全性以及出色的柔韧性,被认为是一类非常有应用前景的固态电解质.但是,其固有的半结晶特性以及较差的力学性能导致它们在室温下的离子电导率较低,并且在高温下不能有效地抑制锂枝晶生长.为改善上述问题,本文设计并合成了一种新型的珊瑚状Li_(6.25)Al_(0.25)La_(3)Zr_(2)O_(12)(C-LALZO)活性陶瓷填料来增强PEO聚合物电解质,制备得到的复合固态电解质(PLC)表现出更高的离子电导率和机械强度,保证了锂金属的均匀沉积/剥离.采用PLC的锂对称电池在60℃下循环1500小时不发生短路.组装得到的LiFePO_(4)/PLC/Li全固态电池在60和50℃时均有出色的循环稳定性.这项工作表明,通过调节填料的微观结构(如C-LALZO结构),可以有效地改善复合电解质的电化学性能.

摘要：This study firstly defines a set of arrangement rule for perforated holes of multi-hole orifice(MO), and then presents three critical geometrical parameters including total number of performated hole, equivalent diameter ratio and distribution density of perforated holes, which are to quantify MO structure. This paper built the throttling test apparatus for nice test MO plates, which were designed according to orthogonal theory. The experiments were conducted to investigate the effect of three critical geometerical parameters on the pressure loss coefficient of test MOs. Results show that equivalent diameter ratio is the dominant prameter affecting MO throttling characterstic.

摘要：Asteroid exploration is one of the most sophisticated missions currently being investigated. Gravity-assist trajectories have proven valuable in interplanetary missions such as the Pioneer, Voyager and Galileo. In this paper, we design interplanetary trajectory for main belt asteroid exploration mission with the Mars gravity-assist (MGA) using “pork chop” plots and patched-conic theory and give some initial valuable trajectory parameters on main belt asteroid exploration mission with MGA.

摘要：Placement and wiring of vast amount of sensor elements on the 3-dimensionally configured robot surface to form soft sensor skin is very difficult with the traditional technology. In this paper we propose a new method to realize such a skin. By implanting infrared sensors array in an elastic body, we obtain an elastic and tough sensor skin that can be shaped freely. The developed sensor skin is a large-area, flexible array of infrared sensors with data processing capabilities. Depending on the skin electronics, it endows its carrier with an ability to sense its surroundings. The structure, the method of infrared sensor signal processing, and basic experiments of sensor skin are presented. The validity of the infrared sensor skin is investigated by preliminary obstacle avoidance trial.
