Question: A feedback control system is shown helow. a . ( 2 points ) What type of controller is shown? PD b . ( 3 points

A feedback control system is shown helow.
a.(2 points) What type of controller is shown?
PD
b.(3 points) Is the plant stable or unstable? Why or why not?
unstade
c.(10 points) Assuming K2=2, determine the controller gain K1 so that the system response will be critically damped. (You may ignore any numerator dynamics.)
d.(3 points) This controller will have numerator dynamics. How could use the same type of controller, but have no numerator dynamics? (HINT: Remember the homework!)
