MATLAB: How to have a Transfer Function with delays in a Simulink model using Simulink 4.1 (R12.1)

Question

I have a Transfer Function that contains multiple exponential functions such as exp(-qs) which means in the time domain there is time delay. I would like to know how I can put such Transfer Function into a Simulink block.

Answer 1

You can use the LTI System Block that comes with the Control System Toolbox. This block will accept any TF,SS or ZPK LTI model. So as long as you can model your Transfer Function using the TF function, you can use this Transfer Function in this block. This example model has a Transfer Function with a 2 second delay on the input.
