How does one setup the requirement optimization function for Optimizing the Battery Design through Response Optimization App on Vehicle Composer ?
The function is of the nature : min f(x) = w1*ECR + w2*Cost
I have run the baseline simulation, now I want to do a optimization study, But I am new to this enviroment and I am trying to understand how does one setup the Optimization function for the EV.

Hi @Shardul
I didn't watch the video. However, with the cost function, you apply the optimizer:
fun = @costfun;
x0 = 1;
A = -1;
b = 0;
x = fmincon(fun, x0, A, b)
Local minimum found that satisfies the constraints. Optimization completed because the objective function is non-decreasing in feasible directions, to within the value of the optimality tolerance, and constraints are satisfied to within the value of the constraint tolerance.
x = 2.4723
% Cost function
function J = costfun(x)
w1 = 1; % a constant
w2 = 1; % a constant
ECR = x.^2 - 5*x + 6; % a formula in terms of x
Cost = tanh(x).^2; % a formula in terms of x
J = w1*ECR + w2*Cost;
end
