时域有限差分法三维自由空间传播电磁场场分布(Finite Difference Beam Propagation Method)

本人自编的一个快速作图，功能强大的matlab GUI 界面程序。其主要功能如下： 1.导入工作空间变量(X,Y)：导入工作空间变量，并提取类型为数组的变量。 2.绘图(plot)：多种模式，包括1对1，1对多，多对多。如x1—y1 x1—y1,y2；x1,x2—y1,y2。 3.快速标准化图形(NormalFig)：快速设置图形格式，以达到论文图片要求。字体大小，线型粗细等 4.可以手动设置格式 5.可以设置为笛卡尔坐标，也可以设置为对数坐标 6.右键执行命令:“Execute”旁的可编辑框，输入命令，右键执行。右键执行的好处是：可以保存变量到工作空间，实现非连续执行命令。 7.符号函数简易绘图(Ezplot)：快速绘制函数图，并可设置区间，区间设置用“ ”隔开。 8.锁定(lock)：锁定，即图形绘制在GUI坐标轴内；解锁，新建Fig，绘制图形，方便输出 9.保持和编辑(Hold,EditPlot)，编译后exe,亦可对图形进行拾取设置 另还有对变量转置等功能。 整个程序中，如操作失误，每处错误都有提示。 (It is a matlab program,which can help you plot beautiful figures easily,or make you learn some programming skills. In a word,it is a useful program and tool.)

本matlab代码主要设计卡尔曼滤波以及多用户检测相关问题(The matlab code design of Calman filter multiuser detection problem)

对机侧系统的仿真包括系统模型的搭建、化简和控制算法的设计。直驱式永磁同步风力发电系统的机侧模型包括风力机模型、永磁同步电机模型和机侧PWM变换器模型。永磁同步电机和机侧PWM变换器模型的数学模型可以化简在一个数学方程中，简化方框图的搭建。控制器的设计目标是控制同步电机的转速实现最大风能的跟踪。(Simulation of the machine side of the system, including structures, simplification and control algorithms designed system model. Direct-drive-side model of permanent magnet synchronous wind power generation system includes a wind turbine model, permanent magnet synchronous motor model and machine-side PWM converter model. Mathematical model of permanent magnet synchronous motors and machine-side PWM converter model can be simplified in a mathematical equation, a simplified block diagram of the building. The controller is designed to control the synchronous motor speed to achieve maximum wind power tracking.)
