By designing the double loop configuration  the autonomous trajectory tracking is realized. The model uncertainty  external disturbance and the senor noise are also taken into consideration. Then the H controller is put forward in the inner loop. An optimal stability augmentation control (SAC) method is used to stabilize the horizon position and keep it away from oscillation. By calculating the nonlinear decouple map  control quantity is converted to the speeds of the four rotors. At last some simulation results and the prototype implementation prove that the control method is effective.   Mechanism of STED microscopy and analysis of the factors affecting resolution (EI CONFERENCE) 会议论文  OAI收割 6th International Symposium on Precision Engineering Measurements and Instrumentation, August 8, 2010 - August 11, 2010, Hangzhou, China Yang P.; Ai H. 收藏  |  浏览/下载：29/0  |  提交时间：2013/03/25 Stimulated emission depletion (STED) microscopy exploits nonlinear saturable optical transition of fluorescent molecules  allowed to overcome Abbe's diffraction-limit and provides diffraction-unlimited resolution in far-field optical microscopy. We elaborate the mechanism of STED and the conditions of depletion. The formula of STED microcopy resolution is deduced through effective point spread function (E-PSF). The STED system resolution is mainly dominated by the quality of the fluorescence depletion patterns in the focal plane. The depletion pattern is mainly affected by STED beam intensity  polarization  phase plate  primary aberrations  STED pulse shape  pulse duration and delay time. In this paper  we found related models and simulate the relationship between the depletion patterns and the parameters  and put forward effective approach to enhance the system resolution. 2010 SPIE.   Synthesis, Light-Emitting, and Two-Photon Absorption Properties of Platinum-Containing Poly(arylene-ethynylene)s Linked by 1,3,4-Oxadiazole Units 期刊论文  OAI收割 macromolecules, 2010, 卷号: 43, 期号: 19, 页码: 7936-7949 Goudreault T; He Z; Guo Y; Ho CL; Zhan HM; Wang QW; Ho KYF; Wong KL; Fortin D; Yao B; Xie ZY; Wang LX; Kwok WM; Harvey PD; Wong WY 收藏  |  浏览/下载：23/0  |  提交时间：2012/04/25 MOLECULAR-ORBITAL METHODS  2  5-BIS(4-PYRIDYL)-1  3  ORGANIC ELECTROLUMINESCENT DEVICES  4-OXADIAZOLE BPO LIGAND  COMPACT EFFECTIVE POTENTIALS  NONLINEAR-OPTICAL PROPERTIES  DENSITY-FUNCTIONAL THEORY  CONTAINING POLY-YNES  EXPONENT BASIS-SETS  GAUSSIAN-TYPE BASIS  COORDINATION POLYMERS   Prediction of Effective Moduli of Carbon Nanotube-Reinforced Composites with Waviness and Debonding 期刊论文  OAI收割 Composite Structures, 2009, 页码: 274-281 作者:  Shao LH;  Luo RY;  Bai SL;  Wang J 收藏  |  浏览/下载：1102/114  |  提交时间：2009/08/03 Carbon Nanotube  Composite  Waviness  Debonding  Effective Modulus  Nonlinear Elastic Behavior  Mechanical-Properties  Polymer Composites  Fiber Waviness  Matrix Composite  Nanocomposites  Fabrication  Inclusions  Stiffness  Model
