PSO优化BP的源程序,加上作者的注释.(BP PSO optimization of the source, together with the author' s comments.)

用几种函数实现傅里叶变换，变换后可输出图形(With several functions for Fourier transform, transform graphics output)

自建的风力机模型，估计是垃圾，大家可以看看(Self-built wind turbine model was estimated to be garbage)

说明：  中文的基于matlab得直升机模拟，做的还行，就是有点假，实现没有只有他自己知道。(A helicopter flight control system simulation software package was introduced, which was developed on MATLAB 6.5. Several unit math models and system simulation were introduced. The software has made good effect on designing one helicopter flight control system. It is helpful for designing and velidating the control law of helicopter.)

一般的esprit算法计算复杂度高，在计算子空间是算法比较烦，改一些矩阵算法可以减少其复杂度。(Esprit general algorithm of high computational complexity in the calculation of subspace algorithms trouble is, some matrix algorithm can be changed to reduce its complexity.)

粒子滤波matlab仿真程序.粒子滤波的基本思想是：首先依据系统状态向量的经验条件分布，在状态空间抽样产生一组随机样本集合，这些样本集合称为粒子；然后根据观测值不断调整粒子的权重大小和样本位置；最后通过调整后的粒子信息修正最初的的经验条件分布，估计出系统状态和参数。该算法是一种递推滤波算法，可以用来估计任意非线性非高斯随机系统的状态和参数。 粒子滤波主要有三步基本操作：采样（从不含观察值的状态空间产生新的粒子）、权值计算（根据观察值计算各个粒子的权值）、重采样（抛弃权值小的粒子，使用权值大的粒子代替），这三步构成了粒子滤波的基本算法。 SIRF(Sample Importance Resampling Filter)算法是粒子滤波的一种基本算法。(Particle filter matlab simulation program)
