这个文档里的东西讲得是单边MPC控制，欢迎大家下载交流。(This document, the things said to be unilateral MPC control, welcome to download exchange.)

基于ANSYS APDL二次开发的航电设备的动力学扫频分析，载荷输入条件为交越频率以下为恒定位移，交越频率以上为恒定加速度。我将加速度输入转换为位移输入，将位移和加速度两段输入载荷统一按照位移载荷输入，将位移存入表数组，利用ANSYS APDL自动将扫频范围内的位移载荷存入表数组，并循环加载计算，实现了该工程结构的正弦扫频振动分析。(Kinetic sweep analysis, load input conditions of secondary development based on ANSYS APDL avionics for the crossover frequency less constant displacement, above the crossover frequency is constant acceleration. I will convert the input displacement input acceleration, displacement and acceleration loads unity in accordance with the displacement of the two input load input, the displacement of the array into the table using ANSYS APDL automatically load displacement within the sweep range of the array into the table, and cyclic loading calculated to achieve a swept sine vibration of the project structure.)

自编实现快速fft程序，速度较调用系统的fft稍慢(Fast fft own procedures, faster than the system call fft slower)

approximate the integral of exp(x)/(1+exp(x) )* N(m,ss)

说明：  matlab的function，计算hurst指数(matlab' s function, calculated hurst index)

说明：  实现信号的频谱分析，性能分析，产生几个波形(For signal spectrum analysis, performance analysis, resulting in several waveform)

Algorithm Collections for Digital Signal Processing and Matlab applications

说明：  用matlab编写的fft快速傅立叶变换及逆变换函数,其中flip1是供ditfft函数调用的倒叙子函数。(using Matlab fft prepared by the fast Fourier transform and inverse transform function, which is flip1 ditfft function call for the Warrior unreachable.)

说明：  这是一个matlab小程序,可用于求解微分方程,特别是抛物型的微分方程(Matlab This is a small program that can be used to solve differential equations, in particular the type of parabolic differential equations)
