Dears,
I have do simulate in simulink a system with internal delay, for example G(s)= a(s)/(b(s)*exp(-tau*s)+c(s)), is it possible in simulink? Like by command line? Without pade approximation.
I've tried some trick with blocks (feedback, parallel etc..) but it did not work.

You can create a transfer function or state space model in MATLAB using the control system toolbox. Then import that into Simulink using the LTI System block. The workflow is explained here .

I've already tried this way. But my system (fourth order) looks like G(s)=(s+1)/((s+1)+(s+2)*exp(-s)). The LTI system works in command line (because, intrisically, the system is made an state space models) however doesn't in simulink (there's an error like "more zeros than poles").
