From SS model equation I have to find TF

A=-b/m
B=1/m
c=1
D=0

The result given in the book is P(s)=(1/ms + b).

Wolfram alpha throws an error saying that it could not understand my input. Please see attached formula.

Thanks.

is it possible to see the step by step simplification of the "Simplify@TransferFunctionModel[ss]"? If yes then I would like to take the pro.

Sorry, but I do not know anything about Wolfram Alpha and the pro. I only use Mathematica itself. May be someone else would know about showing the steps and answer you.

A0 = {{-b/m}}; B0 = {{1/m}}; C0 = {{1}}; D0 = {{0}};
ss = StateSpaceModel[{A0, B0, C0, D0}];
Simplify@TransferFunctionModel[ss]
