Question

When the period of the observation is large, the type of the error will be:

(a) Transient error

(b) Steady state error

(c) Half-power error

(d) Position error constant

I got this question in an interview.

The origin of the question is Time Domain Analysis in section Stability in Frequency Domain of Control Systems

Answer 1

Right choice is (b) Steady state error

For explanation I would say: The error will be the steady state error if the period of observation is large as the time if large then the final value theorem can be directly applied.
