3阶iir滤波器设计，不采用matlab自带的滤波子程序，完全自己编写程序，可以十分方便的转化为c语言。(3-order IIR filter design, do not use built-in filtering matlab Subroutine entirely their own programming, can be transformed into a convenient c language.)

fdtd 一维程序，用来计算一个点源的程序(fdtd a peacekeeping procedures used to calculate a point of procedure)

帮朋友写的主成分分析，有图形显示，注意请自行判断数据是否需要转置。(Help a friend wrote principal component analysis, a graphic display, attention please judge for themselves whether the data needs to transpose.)

说明：  通过设计模糊PID控制器，实现对直线、圆轨迹较为精准的跟踪(By designing a fuzzy PID controller, the accurate tracking of straight and circular trajectories can be achieved.)

说明：  应用MATLAB编辑的支持向量机的应用程序，能进行预测。(Application of MATLAB support vector machine editing applications, capable of prediction.)

大功率分布式发电系统通常采用三相逆变器并网，由于三相逆变器系统参数耦合，传统方法设计的控制器算法复杂。在d。q坐标系下为双模式三相并网逆变器的独市和并网模式建立了数学模型．采用新的解耦方法，依据独立和并网模式控制系统超调量越小，模式切换过程中被控量的波动越小。切换过程就越平滑的原则。完成了两种模式的控制器设计，即分别应用积分环节、比例环节即可将独立模式和并网模式整定成典型的二阶系统，控制器设计简单．能取得优良的动、静态特性。仿真与实验验证了设计方法的正确性和可行性。(It is necessary to research on three—phase grid-connected inverter which a8 an important part of distributed generation．The parameters of three—phase inverter are coupling．The traditional design algorithm of the controller is complicated．The mathematicM models of stand—alone mode and grid—connected mode are established in d，q fhme． Based on the principle that the lower overshoot of the controller system，the smaller fluctuation of the controlled vailables， the smoother in transfer，controllers of two modes are designed separately，as integral and proportional regulators are separately added to stand-alone mode and g而d—connected mode．The controller has good dynamic and static char— acteristics．Simulation and experimental results varify the correctness and feasibility of the proposed method．)
