Consider the closed-loop control system shown in Figure CP4.5. Develop an m-file script to assist in the search for a value of k so that the percent overshoot to a unit step input is greater than 1%, but less than 10%. The script should compute the closed-loop transfer function T(s) = Y(s)/R(s) and generate the step response. Verify graphically that the steady state error to a unit step input is zero.
