Description: 介绍混沌通信同步问题，基于LORENZ MODEL-Abstract—In order to realize chaotic synchronization with less
time and better capability, a method which combining linear
feedback control and response system is studied in this paper
based on Lorenz chaotic model . First of all, chaotic
synchronization is realized by a driver-response model. Next,
on the basis of this model, a method of linear feedback control
is proposed to reduce the synchronization time. And then, the
range of control parameters is given to achieve the Lorenz
chaotic system synchronization, and furthermore, based on
theoretic analysis, simulation results had shown its capability is
satisfying and will have a perfect application prospect when
applied in the fields of chaotic communication due to its perfect
performance, and finally one of its application of this model is
given. Platform: |

Description: 在WPF中，控件（control）一词的意义，比早期Windows编程的控件，有更特定的定义。比方说，在Windows Forms中，屏幕上的一切，都被视为控件。在WPF中，这个词保留给用户交互使用，也就是说，当用户用鼠标或键盘时，控件一般会对用户提供某种响应（feedback）。
Control类直接继承FrameworkElement，从Control继承而来的类超过50个，这些类提供给程序员各式各样的控件，包括按钮、列表框、滚动条、编辑框、菜单和工具条。这些类都是放在System.Windows.Controls与System.Windows.Controls.Primitives命名空间中。这些命名空间也包含一些不是继承自Control的类。
最经典的控件是按钮，在WPF中是Button类。
例子是点击按钮的时候，显示Image图片。-In WPF, control (control) a word meaning, than early Windows programming controls, have more specific definition. For example, the Windows Forms, screen, all be regarded as controls. In WPF, the term reserved to the user interaction use, that is, when the user with the mouse or keyboard, controls will generally provide some response (to the user feedback).
Control class directly inherited from FrameworkElement, inherit the Control of more than 50 of these classes are provided to programmers various controls, including button, list box, the scroll bar, edit box, menu and toolbar. These classes are on the System Controls with Windows. J j j j Windows Controls views Primitives namespace. These namespace also contains some not inherited from the Control of classes.
The most classical control is Button, in this class is WPF.
Example is click on the button, display add pictures.

Description: In this paper, in control theory, sliding mode control, or SMC, is a form of variable structure control (VSC). It is a nonlinear control method that alters the dynamics of a nonlinear system by application of a high-frequency switching control. The state-feedback control law is not a continuous function of time. Instead, it switches from one continuous structure to another based on the current position in the state space. Hence, sliding mode control is a variable structure control method. The multiple control structures are designed so that trajectories always move toward a switching condition, and so the ultimate trajectory will not exist entirely within one control structure. Instead, the ultimate trajectory will slide along the boundaries of the control structures. The motion of the system as it slides along these boundaries is called a sliding mode and the geometrical locus consisting of the boundaries is called the sliding (hyper) surface Platform: |
