Hello I am trying to implement a transfer function with an exponential and use it as a block in matlab simulink .

How do i express the transfer function H(s)=(1 - exp(-0.01s))/s and add the transfer funtion H(s) in simulink as a block?

Thank you for the help.

Exponential term is simply a time delay so you can treat your transfer function as; H(s) = 1/s - exp(-0.01s)*(1/s)

The 1/s transfer functions can be implemented using transfer function block and the exp(-0.01s) can be implemented using transport delay block.

You mgiht also want to look at this page for more details.

Thank you for the help. I will try that.

Thank you so much.

You can also use the LTI block of the control system toolbox to implement it:

tf(num,den, 'InputDelay', 0.01)
