Sliding mode control is presented based on the kinematics models analysis. Switching function of sliding model control is designed according to back-stepping method. Trending law control is selected to improve the system dynamic performance. In order to solve the constant speed problem caused by conventional trending law control  fuzzy control is used to adjust trending speed in the real time. The simulation results demonstrate that the fuzzy sliding mode controller improves the rapidity of trajectory tracking  and reduces the tracking error and the chattering of the control output. 2012 IEEE.   Dark Energy 期刊论文  OAI收割 COMMUNICATIONS IN THEORETICAL PHYSICS, 2011, 期号: * 作者:  Li, M;  Wang, Y 收藏  |  浏览/下载：28/0  |  提交时间：2013/05/17 EQUATION-OF-STATE  GAMMA-RAY BURSTS  HUBBLE-SPACE-TELESCOPE  GENERALIZED CHAPLYGIN-GAS  DIGITAL SKY SURVEY  MICROWAVE BACKGROUND ANISOTROPIES  BARYON ACOUSTIC-OSCILLATIONS  PROBE WMAP OBSERVATIONS  LARGE-SCALE STRUCTURE  COSMOLOGICAL CONSTANT PROBLEM   SOME REMARKS ON DARK ENERGY MODELS 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF MODERN PHYSICS D, 2011, 卷号: 20, 期号: 8, 页码: 1313-1325 作者:  Cai, RG 收藏  |  浏览/下载：17/0  |  提交时间：2013/05/17 DIGITAL SKY SURVEY  COSMOLOGICAL CONSTANT PROBLEM  HIGH-REDSHIFT SUPERNOVAE  PROBE WMAP OBSERVATIONS  HUBBLE-SPACE-TELESCOPE  DATA RELEASE  COSMIC ACCELERATION  CONSTRAINTS  GRAVITY  COMPONENT   Method for obtaining real temperature of space object by using the ratio of emissivity at different wavelengths (EI CONFERENCE) 会议论文  OAI收割 4th International Symposium on Advanced Optical Manufacturing and Testing Technologies: Optical Test and Measurement Technology and Equipment, November 19, 2008 - November 21, 2008, Chengdu, China Guo-Qiang W.; Tao C.; Jian-Li W. 收藏  |  浏览/下载：33/0  |  提交时间：2013/03/25 The infrared radiation character (temperature and efficiency radiation area) of a space object is an important characteristic  we can judge the state of the object working in orbit by measuring temperature and variety. Due to lower temperature of the object and far distance between the object and the earth  the infrared radiation signal is faintness  therefore temperature and the infrared radiation character is difficult to measure. There are several methods to measure the temperature of the object in theory and each one has its applicability respectively  such as applying Wien Law to compute temperature  based on Stefan-Bolzmann law to compute temperature and utilizing multi-spectrum detector to measure temperature As a whole these methods are based on the hypothesis that the object is a Black-body or the radiance emissivity is constant. In fact  homochromatic radiance of object is not a constant but a function that changes with wavelength. Since the problem that an object whose homochromatic radiance s not a constant which results in temperature can not be computed accurately  we bring forward a method to contrast the luminance of the object at different wavelengths and deduce the relationship among homochromatic radiance and wavelength and the temperature of Black-body  from which we can compute real temperature of object. 2009 SPIE.   Agegraphic dark energy as a quintessence 期刊论文  OAI收割 EUROPEAN PHYSICAL JOURNAL C, 2008, 卷号: 54, 期号: 2, 页码: 303-309 作者:  Zhang, Jingfei;  Zhang, Xin;  Liu, Hongya;  Zhang, JF , Dalian Univ Technol, Sch Phys & Optoelect Technol, Dalian 116024, Peoples R China   |  收藏  |  浏览/下载：15/0  |  提交时间：2012/08/02 Equation-of-state  Karolyhazy Uncertainty Relation  Cosmological Constant Problem  Digital Sky Survey  Accelerating Universe  Coupled Quintessence  Cosmic Coincidence  Model  Consequences  Constraints   Cheng-Weyl vector field and its cosmological application 期刊论文  OAI收割 JOURNAL OF COSMOLOGY AND ASTROPARTICLE PHYSICS, 2007, 期号: 9, 页码: - 作者:  Wei, H , Tsinghua Univ, Tsinghua Ctr Astrophys, Dept Phys, Beijing 100084, Peoples R China;  Wei, Hao;  Cai, Rong-Gen   |  收藏  |  浏览/下载：22/0  |  提交时间：2012/08/02 Dark Energy-model  Equation-of-state  Viscous Modified Gravity  High-redshift Supernovae  Hubble-space-telescope  Accelerating Universe  Coincidence Problem  Constant Problem  Phantom Divide  W=-1 Barrier   String scale gauge coupling unification with vector-like exotics and noncanonical U(1)(Y) normalization 期刊论文  OAI收割 INTERNATIONAL JOURNAL OF MODERN PHYSICS A, 2007, 卷号: 22, 期号: 32, 页码: 6203-6218 作者:  Li, Tianjun;  Barger, V.;  Jiang, Jing;  Langacker, Paul;  Barger, V , Univ Wisconsin, Dept Phys, 1150 Univ Ave, Madison, WI 53706 USA   |  收藏  |  浏览/下载：27/0  |  提交时间：2012/08/02 Strong Cp Problem  Standard Model  Supersymmetry Breaking  Particle Physics  Constant Unification  Moduli Dependence  Grand Unification  Gut Breaking  Condensation  Conservation
