How to use the correct process transfer function?

Hi,

I am trying to simulate different PID control methods in Simulink using a step input, the PID block, a transfer function and a graph to display the results.

For the process I think the transfer function needs to be 1/1+ts for the real world application of a heater.

How do I apply the transfer function to the application to get an accurate result? Or can I use the standard form 1/1+ts?

Any help will be much appreciated.

You can use the transfer function block . In the block dialog you can specify numerator as 1 and denominator as [t 1].
