DPD_sim
Digital Predistortion of Nonlieaner RF Power Amplifier with Memory Effects.
This M code simulates a DPD technique linearization for a AB-class nonlinear HPA with memory effects. Here we consider a memory polynomial predistorter to modeling nonlinearity characteristics and memory effects of a HPA.Simulation procedures divided into three separate parts:
1)Analog imperfection compensation for the direct upconversion transmitter
2)Design a DPD based on a memory polynomial predistorter
3)Performance evaluation via a number of parameters such as:EVM,PSD,SNR,

四旋翼无人机
四旋翼无人机SIMULINK建模,PSO_SA优化PID参数
reverse.m
作用:将History表中的string形式的key值转换为赋给九个全局变量temp00, ... ,temp08运行sum1.slx,可以直接观察此组参数的波形。
History
作用:映射表,将一组参数(temp00, ..., temp08)映射到这组参数的ITAE指标。
trojectory.m
作用:定义一条路径并进行路径压缩,通过不断向sum.slx传递位置参数,控制无人机运动,并接受无人机运动过程,做出无人机运动位置图像。
sum1.slx
作用:从外部接受一组位置关系(x,y,z),模拟无人机由原点(0,0,0)运动到该位置并保持稳态这个过程中无人机的位置变化,并向外部反馈。
PSO_3D.m
作用:调用sum3D.slx,通过PSO得到内循环最优解的参数。
sum3D.slx
作用:获取.m文件中设置好的全局变量的值,模拟内循环三个角度的变化。
PSO_History.m
作用:调用sum9D.slx,通过PSO得到外循环最优解的参数,此过程已被History表优化。
PSO_SA.m
作用:调用sum9D.slx,通过PSO得到外循环最优解的参数,此文件在PSO_History.m基础上被模拟退火算法优化(Four rotor UAV SIMULINK modeling, PSO_SA optimize PID parameters)
