Question:

A closed-loop system is shown in Figure AP5.2. Plot the response to a unit step input for the system for Ñ‚z = 0, 0.05, 0.1, and 0.5. Record the percent overshoot, rise time, and settling time (with a 2% criterion) as Ñ‚z varies. Describe the effect of varying Ñ‚z. Compare the location of the zero -1/Ñ‚z, with the location of the closed-loop poles.
