遗传算法的电机优化程序,个人专门编写的,对于初学者来说,可以借鉴(function youhua1()
遗传算法
n-- 种群规模
ger-- 迭代次数
pc--- 交叉概率
pm-- 变异概率
v-- 初始种群(规模为n)
f-- 目标函数值
fit-- 适应度向量
vx-- 最优适应度值向量
vmfit-- 平均适应度值向量
clear all
close all
clc 清屏
tic 计时器开始计时
n=20 ger=100 pc=0.9 pm=0.1 初始化参数
生成初始种群
v=init_population(n,44) 得到初始种群,22串长,生成20*22的0-1矩阵
[N,L]=size(v) 得到初始规模行,列
disp(sprintf( Number of generations: d ,ger))
disp(sprintf( Population size: d ,N))
disp(sprintf( Crossover probability: .3f ,pc))
disp(sprintf( Mutation probability: .3f ,pm)) sprintf可以控制输出格式
待优化问题)

在计算机上产生一组实验数据,首先产生一段零均值白噪声数据u(n),令功率为 ,让u(n)通过一个三阶FIR:
得到y(n). .y(n)上加三个实正弦信号f1’=0.1,f2’=0.25,f3’=0.26调整 和正弦信号幅度信噪比大致为10dB,50dB,50dB. (1) 令N=256,描绘xn波形;
(2)得出真实功率谱密度 .
(3) 利用此实验数据Pisarenko谐波分解法估计该实验数据的正弦频率及幅度。
(On the computer to generate a set of experimental data, first generate a zero mean white noise data u (n), so that power, let u (n) through a third-order FIR: get y (n).. Y (n) added three real sinusoidal signal f1 ' = 0.1, f2' = 0.25, f3 ' = 0.26 and sine signal amplitude adjustment signal to noise ratio is approximately 10dB, 50dB, 50dB. (1) that N = 256, depicted xn waveform (2) the true power spectral density obtained. (3) using this experimental data, Pisarenko harmonic decomposition method to estimate the experimental data of the sinusoidal frequency and amplitude.)
