USB-SERIALch340 串口驱动（ok）

等高线拟合源代码（matlab源码），老外编的，水平确实可以，佩服。里面注释挺详细了。(contour fitting source code (Matlab source), a foreigner series, level really can admire. Inside Notes quite detailed.)

这是基于MapX4.0的房屋测绘管理信息系统，直接运行工程文件可以实现。(This is based on the Survey and Mapping MapX4.0 housing management information system, run the project file directly can be achieved.)

说明：  用于面板数据平稳性问题（单位根）的MW检验(MW test for panel data stationarity (unit root))

A、名称：限幅滤波法（又称程序判断滤波法） B、方法： 根据经验判断，确定两次采样允许的最大偏差值（设为A）， 每次检测到新值时判断： 如果本次值与上次值之差<=A，则本次值有效， 如果本次值与上次值之差>A，则本次值无效，放弃本次值，用上次值代替本次值。 C、优点： 能有效克服因偶然因素引起的脉冲干扰。 D、缺点： 无法抑制那种周期性的干扰。 平滑度差。(A. Name: Limited filter method (also known as program judgement filter method) B. Method: Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined. Judge each time a new value is detected: If the difference between the current value and the previous value is <=A, the current value is valid. If the difference between the current value and the previous value is greater than A, then the current value is invalid, abandon the current value and replace the current value with the last value. C. Advantages: It can effectively overcome the impulse interference caused by accidental factors. D. Disadvantages: That periodic interference cannot be suppressed. The smoothness is poor.)

PMSM控制系统采用速度电流双闭环矢量控制调速系统，即控制系统中有速度调节器和电流调节器。(PMSM control system adopts speed and current double closed-loop vector control speed regulation system, that is, speed regulator and current regulator are included in the control system.)
