Problem 6.64PP
Assume that the system
has a 0.2-sec time delay {Td = 0.2 sec). While maintaining a phase margin > 40°. find the 
maximum possible bandwidth by using the following;
(a) One lead-compensator section
r f - j l f
s + b*
where b/a = 100.
Dc(s) = K -
(b) Two lead-compensator sections
(b) Two lead-compensator sections
whereb/a =10.
(c) Comment on the statement in the text about the limitations on the bandwidth imposed by a 
delay.
