How do you find the dominant pole?

Dominant pole is a pole which is more near to origin than other poles in the system. The poles near to the jw axis are called the dominant poles. Or, get the closed-loop TF from Open loop TF. Determine the poles of the denominators.

What is dominant pole approximation?

The dominant pole approximation is a method for approximating a (more complicated) high order system with a (simpler) system of lower order if the location of the real part of some of the system poles are sufficiently close to the origin compared to the other poles.

How are system poles calculated?

Poles are the roots of D(s) (the denominator of the transfer function), obtained by setting D(s) = 0 and solving for s.

How do you find the dominant pole in Matlab?

You can find the most dominant poles by looking at the pole-zero map... or just the poles... and finding those that are closest to the imaginary axis.
