PID calculations for the _pid structure *a. This function uses the positional form of the pid equation, and incorporates an integral windup prevention algorithim. Rectangular integration is used, so this function must be repeated on a consistent time basis for accurate control.

介绍属性包 IPersistPropertyBag 接口的实现方法和调用方式。属性包,是以“名称 - 值”的方式提供组件持续性的支持,而“名称 - 值”恰恰又适合于用文本方式来表现。下面的片段是在 HTML 中插入 Microsoft MonthView Control ActiveX 控件后的样式:

The cart with an inverted pendulum, shown below, is "bumped" with an impulse force, F. Determine the dynamic equations of motion for the system, and lin earize about the pendulum s angle, theta = Pi (in other words, assume that p endulum does not move more than a few degrees away from the vertical, chosen to be at an angle of Pi). Find a controller to satisfy all of the design re quirements given below.

MVC设计模式早在面向对象语言Smalltalk-80中就被提出并在此后得到业界的广泛接受。它包括三类对象:(1)模型(Model)对象:是应用程序的主体部分。(2)视图(View)对象:是应用程序中负责生成用户界面的部分。(3)控制器(Control)对象:是根据用户的输入,控制用户界面数据显示及更新Model对象状态的部分。本程序尝试用MVC模式制作了一个简单的贪吃蛇游戏。

vb 串口通讯调试方法 现有电子秤一台,使用串口与计算机进行通讯。编写VB程序来访问串口,达到读取电子秤上显示的数据。该电子秤为BE01型仪表,输出为RS-232C标准接口,波特率为300-9600、偶校验、7个数据位、2个停止位。所有字符均发送11位ASCII码,一个起始位。在VB中与串口通讯需要引入控件MSComm串口通讯控件(在Microsoft Comm Control 6.0中)

he LPC932 can be used to create a Pulse Width Modulated PWM signal. That s an analog signal, with only 2 discrete levels, for example 0V and 5V and a constant period. The current value of this signal at a certain poiTnt of time is proportional to its Duty Cycle. That s the High Time during one period divided by the period. It can also be calculated as the average value during a particular period. That means after low pass filtering, (e.g. RC circuit) the signal becomes analog, with an actual value controlled by the microcontroller. The PWM functionality enables the LPC932 to control for example the speed of DC motors or the brightness of electric lighting.

众所周知,C++Builder本身并不提供串行通讯控件MSComm,但我们却可以通过注册后直接使用它。启动C++Builder5.0后,然后选择C++Builder主菜单中的Component菜单项,单击Import Active Control命令,弹出Import Active窗口,选择Microsoft Comm Control6.0,再选择Install按钮执行安装命令,系统将自动进行编译,编译完成后即完成MSComm控件在C++Builder中的注册,系统默认安装在控件板的Active页,接下来我们就可以像使用C++Builder本身提供的控件那样使用新注册的MSComm控件了。(前提条件是你的机子上安装了Visual Basic,或者有它的库)
