首先建立如下Simulink模型：

视频中的脚本如下：

mdlName = 'zeroes_2ndorder';

figure('name','二阶系统增加零点后的影响','units','normalized','outerposition',[0 0 1 1]);

grid on;

legend_index=1;

hold on;

for a = [3,5,10,-3]

    disp(['Running Test Cycle with a =',num2str(a)]);

    load_system(mdlName);

    cs = getActiveConfigSet(mdlName);

    model_cs = cs.copy;

    set_param(model_cs,'MaxStep','0.01');

    simOut = sim(mdlName,model_cs);

    hplot(legend_index)=plot(simOut.logsout{1}.Values);

    hold on;

    legendInfo{legend_index}=(['a=',num2str(a)]); % or whatever is appropriate

    legend(hplot(1:legend_index), legendInfo(1:legend_index));

    drawnow();

    legend_index=legend_index+1;

end

hplot(legend_index)=plot(simOut.logsout{2}.Values);

hold on;

legendInfo{legend_index}=('no zero 2nd order system'); % or whatever is appropriate

legend(hplot(1:legend_index), legendInfo(1:legend_index));

drawnow();

title('Effect of adding a zero to a two-pole system');

xlabel('Time(seconds)','FontAngle','italic');

ylabel('Normalized c(t)','FontAngle','italic');
