How to add a disturbance in a state-space model? in Simulink

When you have the linear model ẋ=Ax+bu+ep, y=cx+dy+fe.

With c=(1 0), d=0, f=0

[MULI]

Hey Aylinne,

If you are planning to add disturbance to the existing state space model, augment the matrices B, D in the “State-Space” block as follows:

B= [B E];

D= [D F];

And while giving inputs use a “Mux” to give input and the disturbance.

Here I am attaching the screenshot regarding its implementation in Simulink.
