Give the transfer function for a proportional integral (PI) controller that will ensure
(a) (
the phase margin of the system remains unchanged. You do not need to plot the system but please
explain your answer.

(b)
Assuming you are implementing an op-amp based PI controller, calculate values for
your capacitor and R₁. Your Rf value is 10k

Expert Solution

Step 1

PI controller refers as proportional plus integral controller. PI controller is designed to decrease steady state error error because in this controller type of system increase.

Op-amp refers as operational amplifier and it is used to amplify weak electric signals.
