The frequency performance of the linear extended state observer (LESO) is analyzed. It is proved that ESO can estimate the required states at the designed speed in spite of a large range of uncertainties. Finally  the results are verified by simulations. 2012 Chinese Assoc of Automati.   Electron transport in polymer-derived amorphous silicon oxycarbonitride ceramics (EI CONFERENCE) 会议论文  OAI收割 作者:  Zhang L.;  Wang Y.;  Wang Y.;  Wang Y.;  Wang Y. 收藏  |  浏览/下载：65/0  |  提交时间：2013/03/25 The electron transport behavior of polymer-derived amorphous silicon oxycarbonitride ceramics is studied by measuring their temperature-dependent electrical conductivities. The experimental results are analyzed using theoretical models. The results reveal that the materials exhibit three conduction mechanisms: conduction in extended states  conduction in band tails  and conduction in localized states. Particularly  it is found that in a low-temperature regime  the conduction of the materials follows a band tail hopping mechanism  rather than the previously assumed variable range hopping mechanism. The results also reveal that energy gaps such as EC-E F and EC-EA decrease with increasing pyrolysis temperature. 2009 The American Ceramic Society.   Photonic band gap structures in the Thue-Morse lattice 期刊论文  OAI收割 PHYSICAL REVIEW B, 2007, 卷号: 75, 期号: 20, 页码: 205109-205109 Lei, HP; Chen, J; Nouet, G; Feng, SL; Gong, Q; Jiang, XY 收藏  |  浏览/下载：84/0  |  提交时间：2012/03/24 CRITICAL WAVE-FUNCTIONS  ELECTRONIC-PROPERTIES  EXTENDED STATES  CHAIN  PROPAGATION  EXCITATIONS  SEQUENCES  SPECTRUM  DISORDER  TRACE   STATE TRANSITION IN A FAMILY OF GENERALIZED FIBONACCI LATTICES 期刊论文  OAI收割 Zeitschrift Fur Physik B-Condensed Matter, 1992, 卷号: 87, 期号: 2, 页码: 223-227 J.
