| 1 | Dynamic feedback robust stabilization of nonholonomic mobile robots based on visual servoing显示文摘This paper investigates the visual servoing robust stabilization of nonholonomic mobile robots. The calibration of visual parameters is not only complicated, but also needs great consumption of calculated time so that the accurate calibration is impossible in some situations for high requirement of real timing. Hence, it is interesting and important to consider the design of stabilizing controllers for nonholonomic kinematic systems with uncalibrated visual parameters. A novel uncertain model of these nonholonomic kinematic systems is proposed. Based on this model, a stabilizing controller is discussed by using dynamic feedback and two-step techniques. The proposed robust controller makes the mobile robot image pose and the orientation converge to the desired configuration despite the lack of depth information and the lack of precise visual parameters. The stability of the closed loop system is rigorously proved. The simulation is given to show the effectiveness of the presented controllers. | Chaoli WANG 1 , Zhenying LIANG 2 , 3 , Qingwei JIA 4 (1.Department of Control Science and Engineering, University of Shanghai for Science and Technology, Shanghai 200093, China 2.Business School, University of Shanghai for Science and Technology, Shanghai 200093, China 3.School of Science, Shandong University of Technology, Zibo Shandong 255049, China 4.Research & Development Centre, Hitachi Asia Ltd, Hitachi Tower, Singapore 049318) | 2010 | 控制理论与应用(英文版)2010，8，2： | 13 |
| 2 | 1000MW单轴多缸汽轮发电机组的开发显示文摘为优化化石燃料电厂的建设投资,在保证高可靠性和高效率的同时,设备的布置应更加合理。因此,1000MW化石燃料汽轮发电机组的布置趋向于从双轴布置改为单轴布置。本文介绍了日立公司开发的1000MW单轴多缸汽轮发电机组部件技术的情况。目前,末级叶片分别为1016mm及1092.2mm的单轴多缸4排汽汽轮机已分别应用到60Hz和50Hz发电机上。 | Yuji Nameki, Takanori Murohoshi Futoshi Hiyama, Kiyoshi Namura -Hitachi Ltd. | 2000 | 国际电力2000，4，1： | 5 |
| 3 | Characteristics and Microstructure of a Hypereutectic Al-Si Alloy Powder by Ultrasonic Gas Atomization Process显示文摘A hypereutectic Al-Si alloy powder was prepared by ultrasonic gas atomization process. The morphologies, microstructure and phase constituent of the alloy powder were studied. The results showed that powder of the alloy was very fine and its microstructure was mainly consisted of Si crystals plus intermetallic compound A19FeSi3, which were.very fine and uniformly distributed. | Jun SHEN Zhuangde XIE Bide ZHOU and Qingchun LI School of Materials Science and Engineering, Harbin institute of Technology, Harbin 150O01.

| 4 | 采用高热导率技术实现电动汽车和混合电动汽车用的高功率密度IGBT模块显示文摘应用于EV/HFV(电动汽车和混合电动汽车)转换系统的IGBT模块,要求其提高功率密度,以能达到缩小系统体积的目标。为了达到这个目标,我们研发了采用高热导工艺的新型的高功率密度的6-型(6-pack)IGBT模块。采取的创新措施有:采用直接冷却系统以消除热脂的热阻;优化了散热器和液体套管的设计;绝缘衬底不采用通常使用的Al_2O_3(氧化铝),而采用了热导率比Al_2O_3高的Si_3N_4(氮化硅);开发了新型焊接材料。研发的新型IGBT模块能用于EV/HFV转换系统的可能性是非常大的。 | Shinichiro Adachi Fumio Nagaune Hiromichi Gohara Takahisa Hitachi Akira Morozumi Akira Nishiura 郑鹏洲(译) | 2013 | 电力电子2013，，3： | 1 |
