Firstly, based on the sliding mode control and backstepping technique, a new attitude tracking controller is derived to control the attitude motion of spacecraft, the stability of the system is analyzed via Lyapunov method and the reaction wheel dynamics is also considered from the real applications point of view. The whole design process is divided into two steps: the first step is to use sliding control technique to design suppositional adaptive variable structure controller; and the second step is to design attitude tracking controller based on SMC and backstepping technique. Numerical simulations are performed to show that both tracking maneuver and vibration suppression can be accomplished effectively.

首先，采用自适应后步法结合主动振动控制技术设计了姿态跟踪鲁棒控制器，基于Lyapunov方法分析了系统的渐近稳定性；在此基础上，显性地考虑了执行机构动态特性问题，将整个设计过程分为两个步骤：第一步采用滑模控制技术设计了变结构虚拟控制器，给出自适应控制律的设计方法；第二步，将后步法与滑模控制技术相结合，设计了姿态跟踪鲁棒控制器，给出飞轮电压的输入算法及稳定性分析；最后，将提出的控制方法应用于挠性航天器的姿态跟踪控制，通过数值仿真对所提方法的可行性与有效性进行分析和验证。

Press bar is a set of long containing Springs, situated at the junction of the 12.2cm×8.8cm, shall be required to work with the help of other power, parallel and reserved the right slot, mounted on the top of dvysocket follows the contours of machine, the paerboard wheel area press bar pressure plate special design and cataplasm round the same calls external stability, adhesive, coating evenly.

触压棒是由一组载有弹簧、长宽约12.2cm×8.8cm的压片所组成，工作时无须再借助其他动力，平行且预留适当缝隙，安装于贴合机糊轮上端，在纸板接触面上，触压棒压板特别设计与糊轮相同的弧度，使压力稳定，黏合剂涂布均匀。

Based on field experiments and theoretical analysis,the sensitivity of TDR to the nature of wave guide materials and to the length of wave guide was studied.

介绍了6050X1型时域反射仪的基本结构和测定土壤含水率的原理，通过试验分析了它对导棒材料性质及导棒长度的灵敏性。

From the central boss at the highest point of the vault, he followed a rib all the way down again to the matching pier on the opposite corner of the crossing.

他的目光在天穹最高点的浮雕那里追踪着其中的一个肋状支撑物向下，到了交叉点对角处与此相对的另一个石柱。shafts 译为&石棒&显然不合适。&棒&在汉语中再大也不会像柱子那么大。可考虑换其他词。

And what leaps out at me from these lolly-stained letters is how much wisdom lies in the unself-conscious observation of kids.

相比之下，这些粘着棒棒糖污迹的信件所透射出来的东西表明孩子们那么的纯真聪慧。

The controller for the inverted pendulum-cart is then designed by using this pole placement method. The design is rather intuitive and simple. The next design for the inverted pendulum is to use two-block and four-block H〓 optimal synthesis methods. The results are then analyzed from the viewpoints of fragility and robustness.

论文又采用H〓的两块问题和四块问题分别对倒立摆系统进行系统性的优化设计，并从脆弱性和鲁棒性两个方面对设计结果进行了分析，指出倒立摆H〓优化设计的主要问题还是没有鲁棒性。
