Ich have got a tranfer function that has a time delay & a PT2. i want
to use a PID to controll the system

how can i make it in Simulink? in a normal m file its no problem...

in --- F(s) --- out

if a make a Step into F(s) it arrives 30 Samples later on the out.
how can i use this two values for the PID.

so just compare nr.1 (in) & nr. 1 at sample 30 (out)....

and make a "controlling-step" every 30 Samples...
