查询词典 first-aid case

Based on the analysis of the mechanism of robot manipulators, a trajectory tracking controlling research model is first built up with ADAMS, and its mathematical model is formulated through the study of robot kinematics and dynamics. After the modeling errors are analyzed in practical robotic systems, a conception of centralized error is brought forward according to the theory of weighting functions. In the case of modeling errors' exist, the robotic uncertain model is derived by introducing an auxiliary control variable into inverse dynamic analysis. The control strategy of robust exponential convergence is applied to the robotic uncertain model, the applicable conditions and the applicable controller with this application are presented. The stable control effect under three main model uncertainties (parametric errors, joint disturbs, joint frictions) are systematically studied on the previously built research model. The problems of robust exponential convergence controller which often results in unstable output and so produces a large relative error when the input trajectory is in a small range are resolved by adjusting the control parameters based on the controller's structure.

本文在机械手的机械结构分析基础上，利用ADAMS建立了用于机械手轨线跟踪控制研究的机械手模型；通过对机器人运动学和动力学问题的研究，建立了机械手研究的数学模型；分析了机器人系统中模型误差的主要来源，根据加权函数法分析，提出了模型集中误差的概念；在存有模型误差的情况下，采用逆动力学结构并引入辅助控制量，由机器人误差模型推导了机器人非确定性模型；提出了采用鲁棒指数收敛法对上述机器人非确定性模型进行鲁棒镇定的控制策略，并给出了对机器人进行鲁棒指数收敛控制时系统不确定因素应满足的匹配条件；针对机械手研究模型，深入研究了鲁棒指数收敛控制器对机器人系统中常见的模型参数误差、关节扰动、关节摩擦等不确定因素的镇定控制效果；针对鲁棒指数收敛控制器易产生控制量振荡的问题以及在小范围内系统轨线跟踪的稳态误差过大问题，本文分别提出了基于控制器结构的控制参数调整法和基于轨线跟踪范围大小的控制参数分段切换法。

Search engine optimizes this concept to be in China now, of promotion pretty good (I think great majority should be attributed to mail of partial Seo company group the contribution) of hair, in every case is price of full contest of Baidu home page, go GG home page looks, having a lot of websites is somebody is being done optimize, the likelihood is Seo company the Seo that also may be company interior education is managing, my the first pace is to check home page of all websites outside catenary, look to whether have group of hair and so on, now nowadays, see certain website has a few W exterior link, I already be accustomed to sth.

现在搜索引擎优化这个概念在中国，推广的不错(我想大多数应该归功于部分seo公司邮件群发的功劳)，但凡是百度首页满竞价的，去GG首页一看，有许多网站是有人在做优化的，可能是seo公司也可能是公司内部培养的seo在治理，我的第一步是查首页所有网站的外链，看看是否有群发之类的，现如今，看到某一个网站有几W条外部链接，我已经习以为常了。
