Convention V-belt Continuously Variable Transmission, shifts gears the travel mechanism property fixed constraint, unable full into full play initiative control advantage, to engine and Transmission on the go to hold optimum match, Also takes into consideration acceleration and fuel consumption performance, so this paper research Motorcycles with an Electronically-Controlled Continuously Variable Transmission shift gears planning, to use motor power screw, we shall revolve motion changes rectilinear motion, to push driving sheaves achieved to change speed ratio; Comparison between analysis convention CVT speed ratio shift gears curves of acceleration and fuel consumption performance optimum curves, use engine can hold high performance output or low fuel consumption region run.

中文摘要传统皮带式无段变速器(Continuously Variable Transmission， CVT)，换档行程由於机械特性的限制，无法完全发挥主动控制的优点，让引擎与变速器随时保持在最佳的匹配状态，同时顾及加速性能与燃油消耗，所以本文主要研究机车用电子控制式无段变速系统(Electronically Controlled Continuously Variable Transmission， ECVT)最佳换档规划，利用马达与动力螺杆，将旋转运动改变为直线运动，以推动主动滑轮达到改变减速比；分析传统CVT减速比换档曲线与最佳化曲线之加速性能及燃油消耗比较，使引擎能够保持较高性能输出或较低油耗区间运转。

The paper proposes a method which uses iteration learning control theory to design correction signal to self servo-writing loop. And the correction process can be used to conditions which precision model of plant can\'t be got. The convergence of iteration process can be proved by theory and experiments.

研究发现，自伺服刻写径向误差消除的过程很类似于迭代控制过程，提出用迭代学习控制算法设计自伺服刻写环路的校正信号，并从理论上证明该校正过程能够很好适应无法获取精确致动器模型的情况，证明了迭代过程的收敛性，实验证明径向误差得到较好抑制。

Since the OGY method needs stable manifold, it can't be applied in controlling hyperchaos which has no stable manifold.

由于OGY方法的控制需要稳定流形，因此对没有稳定流形的情况，即所谓超混沌情况就无法用它控制。

So considering trafficability of every single wheel isn\'t circumspect.If driving force of wheels are not concerted,it will happen that some wheel sinks and can\'t produce driving force since wheel sinks too deeply.

如果车轮驱动力输出不协调控制，在松软月面前进时很容易因为某一个车轮受力过大而导致下陷过深失去驱动能力，使整个月球车无法前进，所以车轮驱动力的协同控制是月球车在不平月面几何通过性的重要保证。

A new fuzzy expert control method was brought forward by synthetically using the techniques of on-line intelligent identification, multi-control-mode, self-decision mechanism and self-adjustment of universe of discourse.

对于一些复杂的被控对象，虽然无法建立定量的、完整的数学模型，但被控对象可测变量与不可测的控制变量之间存在可以"分辨"的对应关系依然是过程控制的重要依据。

ABSTRACT: The UAV navigation system's performance is improved through embedding the geography information model that can process the vector map data in the system by using MapX, In this paper, how to navigate and plan the UAV flight course in the vector map is investigated. The basic control and operation for vector map in the geography information system is introduced, and the flight course is designed and modified in the map. In addition, 2D vector map can't orient UAV in 3D space, so the altitude model is added in the UAV navigation system to realize 3D orientation by integrating 2D vector map with altitude plot. The simulation results in the UAV simulation system indicate that the navigation system can monitor and control UAV efficiently and intuitionally.

使用MapX在无人机导航系统中添加能够处理矢量地图数据的地理信息模块，可以显著地提升系统的性能；文章对如何在矢量地图下进行无人机导航与任务规划进行了研究，完成对地理信息系统中矢量地图的基本控制和操作，并在地理信息图上进行航线的设定与修改；另外，针对二维矢量地图无法对无人机进行三维空间定位的问题，文章通过在无人机导航系统中添加高度位置显示模块，用二维平面地图与高度图相结合的方式来实现对无人机位置的三维定位；通过在无人机仿真实验系统中的使用，证明了该系统能高效、直观地对无人机飞行进行监视与控制。

Perhaps most people are now persuaded that it is possible for a man to have volitional control of his muscles and also to know the physical character of his movements and their consequences for himself and others, and yet be unable to resist the urge or temptation to perform a certain act ; yet many think this incapacity exists only if it is associated with well-marked physiological or neurological symptoms or independently definable psychological disturbances .

也许，大部分人现在相信，对于一个人来说，这样的情况是可能的，即对其肌肉有自愿的控制，并且也知道他的运动及其对于他自身与他人的后果的物理特性，但却无法抵制实施某一特定的行为的迫切要求或诱惑，（这样的情况是可能的，即一个人可以对其肌肉进行自主的控制，并且也明白自己的动作的物理特征以及对于自己和他人所可能产生的后果，但就是抵制实施某一特定的行为的迫切要求或诱惑；）而且，许多人认为，只有其与得到了适当标示的生理学的或神经学上的症状或者可单独界定的生理错乱相联系，才存在这种无能。

Broadly speaking, if an activity involves being exposed to the elements, using specialist equipment to control an inherently incontrollable and unpredictable environment, it is probably an extreme sport.

大体来说，如果一项活动包括了那些被揭露的因素，比如用专家的专业技能来控制那些固有的，不可控制的，无法预测的环境，那它就很有可能是一项极限运动。

Computing any point of intersection of the polytope and the ellipsoid is used in the improved algorithm, instead of that of the intersection of two ellipsoids in ellipsoidal techniques, for calculating the solutions of some initial points where ellipsoidal techniques cannot ensure the existence of the solutions.

对某些采用椭球方法无法求取控制量的解的初始点，在改进算法中，采用了椭球与多面体任意交点求解的算法，代替了椭球方法中用椭球交集求解算法计算控制量。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
