For a plant with a transfer function G(s) in closed-loop under unity feedback as in Fig. 4 :
Determine the range of K to ensure stability of the feedback loop.
ii. It is desired that the percentage overshoot is less than 5%. Find a suitable proportional gain K by using the root locus method. (Show the real axis segments, break away point, asymptotes & J crossing points).
iii. Determine the steady state error then design a controller to eliminate the steady state error.
For a plant with a transfer function G ( s ) in
