Description: 自动控制理论是人类在了解自然和改造自然的过程中逐渐形成的一门学科。简单反馈控制的最早应用，可以追溯到古代亚历山大时期的克泰希比斯水钟，它就是利用反馈原理来调节流量的。19世纪中叶，J.C.麦克斯威尔对具有调速器的蒸汽机（这也利用了反馈原理来调速）系统进行了稳定性的研究。20世纪20年代，布莱克、奈奎斯特和波德在贝尔实验室的一系列研究工作奠定了经典自动控制（反馈）的理论基础------

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 control theory and stability theory, root locus analysis a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system. This is a technique used as a stability criterion in the field of classical control theory developed by Walter R. Evans which can determine stability of the system. The root locus plots the poles of the closed loop transfer function in the complex s-plane as a function of a gain parameter.-In control theory and stability theory, root locus analysis is a graphical method for examining how the roots of a system change with variation of a certain system parameter, commonly a gain within a feedback system.

Description: 在工业应用中PID及其衍生算法是应用最广泛的算法之一，是当之无愧的万能算法，如果能够熟练掌握PID算法的设计与实现过程，对于一般的研发人员来讲，应该是足够应对一般研发问题了，而难能可贵的是，在我所接触的控制算法当中，PID控制算法又是最简单，最能体现反馈思想的控制算法，可谓经典中的经典。经典的未必是复杂的，经典的东西常常是简单的，而且是最简单的，想想牛顿的力学三大定律吧，想想爱因斯坦的质能方程吧，何等的简单！简单的不是原始的，简单的也不是落后的，简单到了美的程度。(PID and its derivative algorithm is one of the most widely used algorithm in industrial applications, the universal algorithm is fully deserve to master, if the process of design and implementation of PID algorithm for general R & D personnel, should be sufficient to deal with the problem of general R & D, and to be valuable, I contacted the control algorithm among them, PID is the most simple control algorithm, control algorithm can best embody the feedback of thought, is the classic classic. Classics are not necessarily complicated. Classical things are often simple, and they are the simplest. Consider the three laws of Newton's mechanics. Think of Einstein's equations of mass and energy, how simple! Simple is not primitive, simple is not backward, simple to the extent of the United states.) Platform: |
