With four different values for the gain K in the controller F(s)
= K/s we get different closedloop poles and so different behaviour
of the closed-loop system.
Find the poles and the step response that correspond to each
value of K. Answer by circling in the table below.
A -3 B -3 -1 ΦΤ 2 -2 2 -2 Im Im Re Re -3 -3 C D X -1 X X 2 -2 2 -2 Im Im Re Re
