自己搭的三相锁相环模拟电路，作业经过运行验证，能够很迅速的锁定电压电流相位。(Take their own three-phase PLL analog circuits, after running the verification, the lock can be very rapid phase of voltage and current.)

svpwm模块，可根据需要形成PWM波形(svpwm block)

说明：  内附几十种小程序，有状态机、比较器、波形发生器、乘法器、加法器、步进电机控制器等，希望大家能用的上。(Containing dozens of small programs, for reference，This is about FPGA,a tool ,we can study,but in ourselves.)

解决多人合作时的利益分配模型,操作简单，模型设计合理。(solving the problem of assignment in cooperation.)

最小一乘算法和最小一乘拟合直线。这是最小一乘拟合直线的matlab算法。(Least absolute deviation fitting algorithm and the least absolute deviation line. This is the minimum by fitting a straight line matlab algorithm.)

通过matlab调用xfoil程序，对翼型升阻力力矩进行计算，并将计算结果生成结果文件，程序中对三种翼型进行了计算，用户可根据需要删减或复制程序的相同部分即可(Xfoil by calling the same part of matlab procedures, the airfoil lift and drag torque is calculated, and the calculated results file is generated, the program for the three airfoils were calculated, the user can cut or copy the program as needed to)

FIR high pass filter...

说明：  matlab经典程序集~~~~~~~~~~~~~~~~~~~~~~~(programs of matlab)

使用最小二乘法对任意位置的椭圆进行数据拟合的程序，使用全部的边缘点集。(Anywhere using the least squares method for data fitting ellipse, the use of all of the edge point set.)
