6.速度

说明：  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.)

this folder contains VIs related to USRP.

说明：  labview 的循环创建数组，并存入电脑excel(The LabVIEW loop creates an array and stores it in the computer Excel)

主要运用labview的编程功能完成对信号的功率谱分析，从而更好的理解功率谱。(The main use labview programming features to complete the signal power spectrum analysis to better understand the power spectrum.)

Labview的EXCEL工具包和实例，几乎包括了所有关于EXCEL的操作，可以作为学习和实际应用的参考(EXCEL toolkits and examples of Labview, including almost all operations on EXCEL can be used as reference for study and practical application)

说明：  生成的波形图表数据自动保存到指定文件夹下面，在数组中时时显示数据。(Generated waveform chart data is automatically saved to the specified folder, and always display the data in the array.)

振动信号的峭度指标在labview中实现，对振动信号的评价很准。(Labview achieve signal kurtosis)

齿轮箱故障诊断的一些集成程序 可以实现齿轮箱的常见分析(Gearbox Fault Diagnosis of some integration program can achieve a common analysis of the gearbox)

说明：  基于LABVIEW软件采集电压电流信号，运用DAQmx建立任务(Acquisition of voltage and current signals)

新建子VI（test2 oise_testing.vi），运用Express VI，实现噪声信号的采集、处理、显示和存储(The new sub VI (test2 oise_testing.vi) uses Express VI to realize the acquisition, processing, display and storage of noise signals)
