系统辨识作业 考虑如下模型 z(k)-1.5z(k-1)+0.7z(k-2)=u(k-1)+0.5u(k-2)+v(k) 其中v(k)是均值为0，方差为1的白噪声。根据模型生成数据，采用递推最小二乘法对模型参数进行辨识，要求绘出各参数随时间的变化曲线。 ("System identification" computer test 。Consider the following model Z (k) to 1.5 of z (k- 1)+ 0.7 z (k- 2) = u (k- 1)+ 0.5 u (k- 2)+ v (k) The v (k) is the mean to 0, the white noise variance 1. Generate data according to the model, the recursive least squares method is adopted to model parameters are identified, draw the parameters changing with time curve. )

autocad生成的.DXF文件转化成G代码，应用于数控编程。(Autocad generated. DXF file into G code, is applied to the numerical control programming.)

这是NURBS曲线的绘制程序，在MATLAB-2008a环境下进行编写，包含了几个基函数子程序。可以通过调节控制顶点和点的权重来调节曲面形状。 (This is a NURBS curve drawing program, in the MATLAB-2008a environments prepared, including a number of basis function subprogram. Can be controlled by adjusting the weight of vertex and point to adjust the surface shape.)

二维图绘制的C#小程序,能生成二维图像。(about Drawing with C#)

说明：  绘制磁滞回线，模拟磁滞回线产生的过程，便于理论分析建模(Drawing hysteresis loops to simulate the process of hysteresis loops is convenient for theoretical analysis and modeling.)

自己在PSCAD中搭建的高压直流输电逆变侧的模块，本模块使用了定电流策略，比较容易上手，适合初学者学习(PSCAD built himself in the side of the HVDC inverter module, the module uses a constant current strategy, relatively easy to use, suitable for beginners to learn)
