A Unity feedback system has an open loop transfer functionof
G(s) = K / s (s+1) (s+5)
Draw the root locus plot and determine the value of K to give adamping ratio of 0.3 A network having a transfer function of 10(1+10s) /(1 +100s) is now introduced in tandem. Find the new value ofK, which gives the same damping ratio for the closed -loopresponse. Compare the velocity error constant and settling time ofthe original and the compensated systems
