Hello everybody, Who can tell me how to declaration e^(-t.s) in matlab simulink? It's a function delay of FOPDT or SOPDT. I have found a document somewhere e^(-t.s) ~ 1/(ts+1), and then: [k.e^(-t.s)]/[s(Ts+1) ] "~" 1/[s.(Ts+1)] x 1/(ts+1) Are they the same? Who can give me a suggest? Thank for reading.
