1. For the following unity feedback system \( G_{c}(s) \) is a PID controller and \( G(s) \) is \( G(s)=1 /[s(s+1)(s+4)] \). a) Draw root locus curve for \( K_{p} \) changes from zero to infinity when \( K_{1}=0 \) and \( K_{d}=0 \). b) Obtain the \( K_{p}, K_{1} \), and \( K_{d} \) values of PID controller by using the \( 2^{\text {nd }} \) Ziegler Nichols Method. c) Draw the modified root locus curve and step response. Do you have a good step response ? d) How could you improve the performance further ? Show on root locus and step response curves.
