How can I use a closed loop for MPC for my use case?

This is not the exact code but a reference code..

function x= mpc(y,..)

Ts=2e-6; %(Sampling time)

tend=0.02;

Nsim=tend/Ts;

y(1)=0.5;(this should be the value only for the first time when in the loop and the next values will be dependent on PWM signals)

x(1)=1;

for i=2:Nsim

x(2)=2*x(1)+5*y(1);

y(2)=y(1)*x(2);

x(2)=x(1);

y(2)=y(1);(This goes as input to other function model which calculates the value of y for next time step)

end

I want at each interval of 'i' the value of y to come out of the loop as for next time instant my value of y changes because the PWM signal of carrier defines the next value of y. Is there any way I can do this?

Any help would be very helpful..

Don't know how to approach your problem as per title. Guess MPC is special function, and PWM is probably a term that denotes the time-varying signal.

The description implies that you want the values of the vector y for every loop.

Can you point out which of the following is the "closed-loop" object?

Ts, tend, Nsim, y(1), y(2), x(1), x(2)

For my MPC control, y is the control input which is a time varying signal. And y(1) denotes y at instant i=1 and the output is the input to a PWM generator which calculates the modulation or dity cycle for next instance.

Maybe inside this loop, you can try calling the function where you want to send the y value.

for i = 2:Nsim
    x(2) = 2*x(1) + 5*y(1);
    y(2) = y(1)*x(2);
    x(2) = x(1);
    y(2) = y(1);    % This goes as input to other function model which calculates the value of y for next time step
end

Is it possible to call a matlab referred simulink function to call in other matlab referred simulink function?

I'm not sure if I understand what you meant. Perhaps you can try the sim() function. Check the details here:
