在您的MATLAB代码中,您尝试通过两个for
循环分别改变光照强度(S)和温度(T),然后对每个条件运行仿真并绘制相应的P-U和I-U特性曲线。然而,代码中的一个关键问题是您没有在每次迭代中保存或更新电压(V)、功率(P)和电流(I)的值。
为了修复这个问题,您需要在每次sim('jzh.slx')
之后读取这些变量的值,并将它们存储在数组中。然后,您可以使用这些数组在for
循环外部进行绘图。以下是修改后的代码:
% Initialize arrays to store V, P, and I values
VP_S = {}; % For storing V and P for different S values
VI_S = {}; % For storing V and I for different S values
VP_T = {}; % For storing V and P for different T values
VI_T = {}; % For storing V and I for different T values
% Loop over different S values
for S = 600:200:1200
T = 25;
% Run simulation
sim('jzh.slx');
% Read voltage, power, and current from the simulation results
V = get_param('jzh/slave', 'Voltage'); % Replace 'slave' with your actual block name
P = get_param('jzh/slave', 'Power'); % Replace 'slave' with your actual block name
I = get_param('jzh/slave', 'Current'); % Replace 'slave' with your actual block name
% Store data in arrays
VP_S{end+1} = [V; P];
VI_S{end+1} = [V; I];
end
% Loop over different T values
for T = 15:5:40
S = 1000;
% Run simulation
sim('jzh.slx');
% Read voltage, power, and current from the simulation results
V = get_param('jzh/slave', 'Voltage'); % Replace 'slave' with your actual block name
P = get_param('jzh/slave', 'Power'); % Replace 'slave' with your actual block name
I = get_param('jzh/slave', 'Current'); % Replace 'slave' with your actual block name
% Store data in arrays
VP_T{end+1} = [V; P];
VI_T{end+1} = [V; I];
end
% Plot curves for different S values
figure(1)
for i = 1:length(VP_S)
plot(VP_S{i}(1,:), VP_S{i}(2,:),'DisplayName',['S=',num2str(S(i))])
end
hold on
axis([0 50 0 400])

这段代码首先初始化了四个空数组来存储不同条件下得到的电压、功率和电流值。接下来,它会遍历不同的光照强度(S)和温度(T),并在每次迭代后读取模拟结果中的电压、功率和电流值。最后,它将这些数据用于绘制多条曲线,每一条代表一种特定的光照强度或温度条件下的P-U和I-U特性曲线。
