对一幅图像实现不同角度的旋转，从而可以观察不同角度的结果。( rotate_image- rotates an image given inside a matrix by the amount of "degree" counter-clockwise using linear interpolation of the output grid points from the back-rotated input points in this way, the output image will never have a "blank" point)

computes the LQG controller parameters, [K1 K2 K3 K4] system states are the HF components of: LSS speed, HSS speed, coupling internal torque, wind torque uses the linearzid WECS model with parameters computed in linf_param_comp.m file uses quadratic performance index with weighting coefficient weight

使用统计方法进行系统不确定性的分析，包含m函数和Simulink模型(Using Statistics for Uncertainty Analysis in System Models)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。正所谓 一分钱一分货啊，优化效果不总是令人满意。(This procedure is the most basic particle swarm optimization procedures, using Matlab implementation, is very simple. Only a few dozen lines of code. One is the so-called sub-penny ah goods, and optimize the result is not always satisfactory.)

说明：  离散系统灰色PID控制,对不确定部分建立灰色估计模型,根据参数的不确定部分进行一定的补偿(PID control of gray discrete-time systems, part of the establishment of the uncertainty estimation model gray, according to the parameters of uncertainty to a certain part of the compensation)

说明：  BPSk信号通过高斯信道的matlab程序的实现(BPSk signal through the Gaussian channel matlab program to achieve)

算法部分是网上下的，因为应用不同，有所改动，界面程序是我自己加的，很简陋，但是能用，有的地方原程序被注释掉了，是为了保持原有程序的语句，怕删掉以后回不去。运行时注意地址和函数调用格式 (poor)
