In Example 10.7.4 the steady-state error for a unit-ramp disturbance is 1/KI.For the gains computed in that example, this error is 1 /25. We want to see if we can make this error smaller by increasing KI. Using the values given for Kp and KD in that example, obtain a root locus plot with KI as the variable. Discuss what happens to the damping ratio and time constant of the dominant root as KI is increased.
