PROBLEMS Problem 1 Consider the feedback system block diagram shown below. a) Convert it to a unity feedback system. (5 points) b) State the system type. (5 points) c) Calculate the static error constants Kpos, Ky and Ka. (5 points) d) What is the steady state error in response to a unit step input? (5 points) e) Use the Routh-Hurwitz stability criterion to determine if this system is stable or not. (5 points) R(s) + Solution: 5 s(s + 1)(s + 2) (s+3) C(s)
