Use Evaluate. Do[Plot[Evaluate@StateResponse[{StateSpaceModel[{amtrx[[i]], b, c, d}], {rad3, rad4}}, M1[t], {t, 0, 5}][[1]], {t, 0, 5}], {i, 9}]

comment How to transform transfer functions into differential equations?
Great! I'm glad it addressed all you needed out of it. The functionality could probably be improved, but I will leave that for another time. And thanks for bringing up the original question.

Phab, I have now added the function to extract numerators and denominators as well. Am I hand-holding too much. Hope you can take it from here.

Updated again. My bad, I was thinking incorrectly about it and passed it to failed. Fixed now.

I have updated the function to handle delays as well. The cases I have not considered are discrete-time systems and multivariable systems.
