PSO algorithm to tuning PID

说明：  利用Matlab编写程序实现以下功能：以多项式形式输入系统前向通路传递函数和反馈回路传递函数，计算系统开环增益，判定型别，根据控制系统劳斯稳定判据原理，列出得到的任意阶次系统的劳斯表，判定闭环系统稳定性，若不稳定给出具有正实部极点的数目。 （1）根据用户输入的稳定度a，计算稳定的开环增益K的范围； （2）确定系统的最大稳定度a,计算相应的开环增益K的值。 (The use of Matlab programming to achieve the following functions: polynomial in the form of input system transfer function to the path and feedback loop transfer function, system open-loop gain calculation to determine type, according to Routh stability criterion control system theory, has been listed in the system of arbitrary order Routh table to determine the stability of the closed-loop system, if the stability of a positive real part gives the number of poles. (1) According to the stability of the user to enter a, calculation of the stability of the open-loop gain of the scope of K (2) to determine the most stable system a, the calculation of the open-loop gain of the corresponding K value.)

在相干通信中精确恢复眼图，使用正弦函数作为例子，经过欠采样后，对数据进行FFT变换后在进行精同步(After the restoration of coherent communications precise eye, using a sine function as an example, after subsampling, FFT transform data during fine synchronization)

This is a matlab code for OSTBC transmitter and receiver

说明：  不变矩是模式识别里面很重要的一种技术，它可以用于提取不变性特征，从而进行模式识别，广泛用于图像处理当中，如图像特征匹配(Moment invariant pattern recognition which is a very important technology that can be used to extract invariant features for pattern recognition which is widely used in image processing, such as an image feature matching)

HL计算工程结构可靠度的简单算例2 包含1.例题文件，2.HL法计算，3.Matab自带抽样，4.自编monte carlo抽样(HL Method and Monte Carlo Method for Solving Reliability Index of Structures)

说明：  matpowe7.0,Open source software, no modified version downloaded from the official website,the new MOST can calculate timing OPF,but the DC model may not be accurate

This Matlab file is intended to demonstrate that the application of Kalman filters to basic linear system is quite easy and its application is optimal under certain conditions.
