Temperature controlstep response for a transfer function
Posted:

Hi,
Having some real problems creating the correct step response figure for the following transfer function:
G(s) = e^(ts) * H/(1+Ts)
so far I can create the step response figure for a simplified transfer function G(s) = H/(ts+1)(Ts+1) by;
in matlab main window: H = 2.08 T = 0.45 t = 0.12 gopen = tf([H],[t*T,T+t,1]) gclose = feedback(gopen,1) step(gclose)
however i'm not sure how to create 'gopen' for the first more accurate transfer function??
i've tried the following but I have no idea which one (if any) is correct!
gopen = tf([exp(t),H],[T,1])
gopen = tf((exp(t))*[H],[T,1])
and
gopen = tf([exp(t)],[T,1])
any help would be really appreciated.
Thanks
Dan
