作者： Yuanqian Li and Wei Liu institute of Automation chinese academy of Science beijing 100190 china

We focus on the object reaching problem for eyeon-hand robot system:how to control the end-effector to reach the exact position and orientation according to the visual information of *** exact position and orientation are defined as"reaching pose"in this *** issues are mainly concerned and this leads to two contributions in this paper:（1） Find the relationship between reaching pose and object pose in the *** traditional methods based on complex calibration,supervised learning algorithm is introduced to learn the relationship based on training data which are collected *** method has two main advantages:1) it can be implemented with little human assistance and 2) it can handle non-linear case.（2） Represent the object pose in the image.A novel and robust algorithm is proposed to extract the feature *** feature points are robust and invariant under translation,rotation and *** those feature points are sorted into a sequence which corresponds to the input-variable *** sequence is also robust to make sure the consistency of the meanings of the input ***,the experiments show the validity of our method.

PRE-ESTIMATE FOR THE CHANGE OF CLIMATIC VULNERABILITY TO AGRICULTURAL PRODUCTION IN LOESS PLATEAU,china

引用

Natural Disaster Reduction in china 2003年第4期 38-41页

作者： Hou Yahong 1 and Liu Wenquan 2 (1. Department of atmospheric sciences of Nanjing University, Nanjing 210008 2.chinese academy of Meteorological sciences, beijing 100081)

In Loess Plateau, which has a vulnerable ecological condition, the influence of climatic change on agricultural production is great. Based on introducing the relative definitions of vulnerability and evaluations and schemes of climatic vuhnerability to agricultural production, this paper makes a preliminary evaluation on the vulnerable condition in 1997; and by using the relative results of GCM pre\|estimate, it estimates the possible changes of related index of the disaster; and estimates the future possible changes of climatic vulnerability to agricultural production in Loess Plateau. Its evaluation method and pre\|estimate results can provide a certain scientific basis to the decision of departments concerned.

作者： Zhang Wenjing Integrate Information System Research Center institute of Automation,chinese academy of sciences,beijing 100080,P.R.china

Dynamic friction and force ripple are the most predominant factors that affect the positioning accuracy of perma- nent magnet synchronous motor servo system,and it is desirable to compensate them in finite time with a continuous control *** this paper,based on LuGre dynamic friction model,an adaptive sliding mode controller is proposed to compensate the nonlinear effect of friction and force *** compensation scheme consists of a PD component and an adaptive sliding mode component for estimating the unknown system *** Lyapunov stability theorem,asymptotic stability analysis and position tracking performance are *** results well verify the feasibility and the effective- ness of the proposed scheme for high-precision motion trajectory tracking.
