数据观

本文针对非线性动态摩擦设计了非线性观测器，以便从输入输出数据观测出非线性摩擦的大小，并对其进行补偿。

In this paper a nonlinear observer is designed for the nonlinear system with nonlinear dynamic friction so that the nonlinear dynamic friction can be estimated using the input and output data and then be compensated .

一旦完成了对GPS信号的捕获和跟踪处理后，得到码相位、多普勒频率和导航数据信息等观测量。

Once acquisition and tracking is achieved , the code phase , Doppler shift and navigation message can be obtained .

同时笔者采用了AHP和灰色关联法对指标数据进行主客观权重运算，得到了以综合评价值最大的组合权重值作为系统初始静态权重。

And then the author used AHP & Gray Correlation Analysis methods to get subjective and objective weight , and calculation the maximum comprehensive evaluation value as the initial static weight .

移动对象数据库系统中存放着大量的关于移动对象位置信息的时空轨迹数据，受到主客观因素的影响，移动对象运行行为具有动态性、不确定性和实时性的特点，需要不断更新位置信息。

It accumulates a large amount of trajectory data relevant the positions of objects in moving objects databases . Due to the subjective and objective factors , the behavior of moving objects has the typical characteristic of dynamic , uncertain , and real time .

通过GPS变形监测网设计的相关理论的研究，设计了适合测区的变形监测网，然后进行了数据采集，并对采集的数据运用观测量优选的方法进行了数据分析。

Through the relevant theoretical research of GPS deformation monitoring network design , design suitable for measuring the deformation monitoring network and then proceed to the data acquisition , data acquisition and measurement of the use of optimization methods for data analysis .

因而，需要根据图像色差的视觉评价数据和基于已有色差公式的计算数据建立主客观评价值之间的联系。

Thus , there is the demand for establishing the link between objective and subjective evaluation value based on visual experimental data and calculation results .
