带滑移铰空间机械臂惯性空间轨迹的复合自适应跟踪控制

讨论了载体的位置与姿态均不受控制的漂浮基带滑移铰空间机械臂的控制问题。动力学分析表明，结合系统动量及动量矩守恒关系得到的运动Jacobi关系及系统动力学方程将是系统惯性参数的非线性函数，借助于增广变量法，我们得到了与惯性参数呈线性关系的系统广义Jacobi矩阵及系统控制方程，以此为基础，针对系统中存在未知惯性参数的情况，设计了一种末端抓手惯性空间期望轨迹跟踪的复合自适应控制方案，此控制方案的优点在于不需要测量空间机械臂载体的位置及移动的速度，加速度，仿真运算证实了方法的有效性。     

SPACE LIFE SCIENCE IN 2000-2001

Chinese scientists studied some of the problems in the field of space life science and achieved success in the area during 2000-2001. Space biological experi ments were carried out in the orbit and the results of ground studies on protein crystallization, space radiation, space motion sickness were introduced in this paper. The influences of simulated weightlessness on the brain-function, the car diovascular, endocrine hormones, immunity, skeletal and muscle systems were presented. In addition, gravity medicine and space environment medicine, as well as countermeasures to space deconditioning, such as the traditional Chinese medicine, were also reported.     

KuaFu Mission

The KuaFu mission-Space Storms, Aurora and Space Weather Explorer-is an "L1+Polar" triple satellite project composed of three spacecraft: KuaFu-A will be located at L1 and have instruments to observe solar EUV and FUV emissions, and white-light Coronal Mass Ejections (CMEs), and to measure radio waves, the local plasma and magnetic field,and high-energy particles. KuaFuB1 and KuaFu- B2 will bein polar orbits chosen to facilitate continuous 24 hours a day observation of the north polar Aurora Oval. The KuaFu mission is designed to observe the complete chain of disturbances from the solar atmosphere to geospace, including solar flares, CMEs, interplanetary clouds, shock waves, and their geo-effects, such as magnetospheric sub-storms and magnetic storms, and auroral activities. The mission may start at the next solar maximum (launch in about 2012), and with an initial mission lifetime of two to three years. KuaFu data will be used for the scientific study of space weather phenomena, and will be used for space weather monitoring and forecast purposes. The overall mission design, instrument complement, and incorporation of recent technologies will target new fundamental science, advance our understanding of the physical processes underlying space weather, and raise the standard of end-to-end monitoring of the Sun-Earth system.

A method for estimation of sea surface temperature, ocean wind speed and water vapor with microwave radiometer data based on simulated annealing is proposed. The proposed method shows about 60% improvement of sea surface temperature estimation accuracy in comparison to the existing method using Newton’s iterative algorithm.     

Progress on Space Solar Telescope in 2004 - 2006

The progress on Chinese Space Solar Telescope (SST) in 2004-2006 is introduced. The scientific objectives are further clarified and the ground operation system has been planned. The 7 key technical problems of SST satellite platform and payloads have been tackled, which lay solid scientific and technological foundations for engineering prototype phase of the SST project. At present the SST project undergoes evaluation by CNSA and CAS so as to enter the engineering prototype phase of the SST project if it is finally approved.
