pid仿真控制器，设计了一个最简单的pid仿真器，并将其模块化(pid emulator)

This program permits you to use FFT under Matlab platform, you may change the fine function used as reference to calculate its FFT to any other function.Hope it helps you.

抛物线法求解 方程的构造方法:给出[0,1]区间上的随机数(服从均匀分布)作为方程的根p*. 设你的班级数为a3,学号的后两位数分别为a2与a1,从而得到你的三次方程 例如:你的31班的12号,则你的方程是21x3+60x2+2x+a0=0的形式. 方程中的系数a0由你得到的根p*来确定.(parabolic equation method Construction Methods : given interval [0,1] on the random number (subject to uniform distribution) as the root equation p*. set up your classes at a3, after learning of the double-digit for a1 and a2, so you get the three equations for example : your 31 classes on the 12th, then your equation is 21x3 60x2 2x a0 = 0 forms. the equation coefficients a0 you get from the root of p* to determine.)

这是我们课程设计时所写的一个OFDM系统仿真程序，OFDM系统仿真.doc是我当时写的设计报告。已通过测试。(This is what we wrote a curriculum designed OFDM system simulation program, OFDM system simulation. Doc is a design report I had written. Has been tested.)

说明：  用双线性变换法设计巴特沃斯滤波器，并模拟相应的图像(Bilinear transformation method with Butterworth filter design and simulation of the corresponding image)

自己尝试编写的核主元分析（KPCA）程序(Try to write a kernel principal component analysis ( KPCA ) program)

五点差分格式解重调和问题，采用适当的技巧将其分解成两个Possion方程求解(Five-point difference scheme solution Biharmonic)

通过B-样条曲线将仅由三维空间中若干点构成的折线轨迹平滑成曲线轨迹，并可视化。可用于机械臂的运动控制规划。(Through the B- spline curve, the curve of the broken line formed by several points in the 3D space is smooth, and can be visualized. Motion control planning for a robot arm.)

在matlab-simulink里搭建的一个三项线路故障模型，可用于故障测距，定位(A three fault lines in matlab-simulink model built in, can be used for fault location, location)

说明：  matlab写的关于BA无标度网络的代码(scale-free complex networks sourcecode)
