Denominator for the nth order inertial term.

Hello,

I was trying to calculate Gain margin by margin(sys) for my

sys = tf(num, dem);

where

num = 1.0506;

My question is how to create denominator for 5th order inertial term with const time T = 4s.

Understood your question correctly, that would be somewhat like e.g.:

num = 1.0506;
SYS = tf(num, [1 1 1 1 1 1/4]);  % 5th order system
margin(SYS)
