PID

Labview，数据采集例程，带子VI，(Labview, data acquisition routines, have SubVI)

数据采集卡采集拉力值，与预先设定的拉力值进行比较，然后PID运算，控制相应的PWM占空比输出，最终控制电机的速度(The data acquisition card collects the pull value and compares it with the pre-set pull value. Then the PID arithmetic is used to control the output of the corresponding PWM duty cycle, and finally the speed of the motor is controlled.)

本vi用于从串口读取十六进制数据并保存数据至tdms文件。用户可在第二个循环中根据自己的串口数据格式进行改动。 （需要安装visa驱动）(This VI is used to read sixteen hexadecimal data from the serial port, and save data to the TDMS file.)

labview读取文件程序，可以读取文件中的任意一段并做频谱分析，并附加了一段参考数据(labview read file program, you can read any section of the file and do spectrum analysis, and additional reference data for some)

labview 计算 CRC ，通过labview 计算CRC 校验(labview COUNT CRC 32BIT LABVIEW)

使用研华采集卡，labview驱动，采集数据和存储，曲线显示(Labview data acq excel save and display)

基于转速环-电流环双闭环控制的直流电机调速系统的labview上位机程序。(The LabVIEW upper computer program of DC motor speed control system based on double closed-loop control of speed-loop and current-loop.)

采集脉搏信号的labview程序,有小波分析(Labview pulse signal acquisition procedure,include the wavelet analysis)

通过编辑注册表的方式，注册ACCESS数据源。(Register the ACCESS data source using the registry)

在波形Graph显件上用两种不同颜色显示一条正弦曲线和一条余弦曲线，每 条曲线长度为128个点，其中正弦曲线的x0 =0，△x=1；余弦曲线的x0 =2， △x=5。并利用属性节点通过前面板控件改变每条曲线的颜色。 ①一个周期128点。 ②改变颜色一定要先选择曲线，然后再改变颜色。(A sine curve and a cosine curve are displayed in two different colors on the waveform Graph display. The length of the bar curve is 128 points, where the sine curve x0 =0, Delta x=1, the cosine curve x0 =2, Delta x=5. And use the attribute node to change the color of each curve through the front panel control. One cycle is 128 points. Change the color must first choose the curve, then change the color.)
