difference-and-fitting-simulation

本文通过matlab仿真，比较线性调频信号的FFT和STFT，并研究了信号中混入各种噪声后如何处理。(In this paper, matlab simulation, comparison of the FFT and linear FM signal STFT, and studied all kinds of noise signals mixed How to handle.)

模式识别工具箱的内容非常好用，找了好久才找到的(The contents of the toolbox is very useful for pattern recognition. Lots of downloads)

基于龙格库塔法的Matlab数值积分函数(Based on Runge Kutta method Matlab numerical integral function )

diagnostic with autocorrelation

可以计算车桥耦合动力响应，得到不同轨道不平顺下的动力响应(The dynamic response of vehicle bridge coupling can be calculated, and the dynamic responses under different track irregularities are obtained)

说明：  粒子群优化方法，并行计算，收敛速度快，利于全局优化，算法实现简单(Particle Swarm Optimization)

time series annalys. Trend decomposyshion. Season index decomposition

开关磁阻电机，直接瞬时转矩控制，速度闭环，三相6/4 SRM Simulink仿真，可用(Switched reluctance motor, direct torque control, closed loop speed, three-phase 6/4 SRM Simulink simulation, available)

该算法利用卡尔曼滤波技术实现GPS静态滤波(The algorithm uses the Kalman filtering technique to achieve static GPS filtering)

this is simple genetic algorithm code
