AP5.3 A closed-loop system is shown in Figure AP5.3.

Plot the response to a unit step input for the system with τp = 0, 0.2, 1, and 4. Record the percent over

shoot, rise time, and settling time (with a 2% crite

rion) as τp varies. Describe the effect of varying τp.

Compare the location of the open-loop pole − /1 τp 

with the location of the closed-loop poles.
