这是一个简单的用于工业进程控制的PID Loop模拟器,在这个例子当中,有一个带有PID Loop水平控件的水槽。这个例子是为了让学生学习到 如何使用计算机来控制工业进程而设计的。用户能处理数值(人工或者自动),以及更改PID值来改变对水槽的控制。对于VB教学来说,它具有浮块控件,窗体图形以及实时的图形化例子。我希望用户觉得这个程序有用- This is simple uses in industry advancement control PID the Loop simulator, in the middle of this example, some has PID the Loop level to control a water trough. How is this example for let the student study uses the computer to control the industry advancement to design. The user can process the value (man-power or is automatic), as well as changes the PID value to change to the water trough the control. As for the VB teaching that, it has floats the block to control, the window graph as well as the real-time graph example. I hoped the user thought this procedure is useful 下载
