how can i get two variables to meet the target SOC which is calculated from simulink.

open_system(mdl)

soc_target = 78.6
off_line = 3000
on_line = 7000


sim(mdl);

while true
      sim(mdl);   
      soc_fin = ans.soc_fin;
      if abs(soc_fin(end)-soc_target) <= 1.5
         break;
      end
      on_line = on_line + 1000;
end

on_line
off_line

while true
      sim(mdl);   
      soc_fin = ans.soc_fin;
      if soc_fin(end)-soc_target < -0.1
         off_line = off_line - 100;

      elseif soc_fin(end)-soc_target > -0.1
         off_line = off_line + 100;    
      
      else abs(soc_fin(end)-soc_target) <= 0.1
          break
      end
end


on_line
off_line

while true
      sim(mdl);   
      soc_fin = ans.soc_fin;
      if soc_fin(end)-soc_target < -0.01
         off_line = off_line - 10;   

      elseif soc_fin(end)-soc_target > -0.01
         off_line = off_line + 10;   

      else abs(soc_fin(end)-soc_target) <= 0.01
          break
      end
end

on_line
off_line

above code is mine that to find

variables on_line & off_line is a number and in simulink model, SOC will be calculated.

when the variables increase, SOC will be decreased,

As variables increase, the soc value decreases, and similarly, as variables decrease, the soc value increases.

i want find two variables to meet SOC target

i'm newly user of matlab so my code is poor

please help.

Hello @Youngjin,

One idea is to integrate your code in the s-function in your simulink file.

Through this idea you can update your variable and your simulink file will run along with the updated values.

You can find the documentation for it in this link - What Is an S-Function? - MATLAB & Simulink - MathWorks France.
