💥1 概述

本文用于准确快速建模光伏模块/组串发生器的NLBBODE优化器及其在解决实际约束优化问题中的应用。

要解决问题，请在“test_case”中选择相应的数字;主代码文件中的第 16 行。问题的顺序如下：

1. 多片盘式离合器制动器设计问题。
2. 减速机设计问题
3. 焊接梁设计问题
4. 拉伸/压缩弹簧设计问题
5. 压力容器设计问题
6. 光伏组件/串建模问题。

主函数代码：

% Settings parameters of Optimizer
    NP=30;            % Number of population(Population Size)   
    nbrloop = 1;     % Number loops (for Standard Deviation StD calculation)
    NFE_max=50000;    % Maximum number of Function Evaluation (Number of Cost function calls)    
    limo = 6000;      % Relative limit for reaching the best NFE
    
%%%%%% Settings for cost function selection
    test_case = 6;    % Put here the number of the problem as mentinned below
    
switch test_case
    case 1
   fun = 1; 
% Cost Function for Multi-plate disc clutch brake design problem

    case 2
   fun = 2;
% Cost Function for Speed reducer design problem     

    case 3
  fun = 3;
% Cost Function for Welded beam design problem       

    case 4
  fun = 4;
% Cost Function for the Tension/compression spring design problem  

    case 5
  fun = 5;
% Cost Function for the Pressure vessel design problem   

    case 6
  fun = 6;
% Cost Function for RMSE_photovmodel (Here the RTC France cell in SDM is chosen, for the other problems go to the RMSE_photovmodel function file and chose the corresponding problem)
    otherwise
          disp('Unkown test case or still under preperation');
          return
end

[Tab_Records,VALI_ind]=NLBBODE(fun,NFE_max,nbrloop,NP,limo);

%% Cost Function Plot (Fitness function graph)
figure1 = figure;
axes1 = axes('Parent',figure1);
hold(axes1,'on');
semilogy(Tab_Records(VALI_ind,:),'DisplayName','A','LineWidth',3);
xlabel('Number of function evaluations');
title('Welded beam design');   
ylabel('Objective function (log)');
xlim(axes1,[0 50000]);
box(axes1,'on');
set(axes1,'FontName','Times','FontSize',12,'YGrid','on','YMinorTick','on','YScale','log');
