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.
