I need to do a P controller, Pi controller and PID controller.

I have a process model with transfer function:

G(s) = Kp

--------------- * exp (-Td * s)

1 + Tp1 *s

I got Kp, Tp1 and Td

I am creating a New script in matlab to obtain the controllers using:

help pade

[num,den] = pade(T,N)

Gp = tf(Kp, [tau 1])

From the Tp1 and Td, which one is T and which is tau?

And how I find the N?
