How can I access future samples of a discrete time signal in Simulink?

Hi

I am busy with a project that implements model predictive control and it uses a reference signal's future sample values, i.e. f(k+1), f(k+2), etc. It is easy to generate and access these values in the MATLAB workspace, since all lines are executed sequentially, e.g. :

• t = 0:0.02:2;
• I_a = sine(2*pi*t);

but Simulink solves all blocks at once. I generate the three-phase signals and convert them to alpha-beta format using the gain, and I want to be able to access the k+1, k+2, etc. timesteps of the two output signals I_alpha and I_beta. See the attached image.
