The Ziegler-Nichols methods are field techniques to obtain PID (Proportional-Integral-Derivative) controller gain values. One of the Ziegler-Nichols methods was applied in an industrial plant. Then, the following figure was obtained after applying a proportional gain equal to 17.5 in a closed-loop transfer function.
Then select the correct alternative.
alternatives
a)The PID controller gains obtained by the tuning method are worth: Kp = 10.5; Ti = 2 and Td = 0.5.
b)The PID controller gains obtained by the tuning method are worth: Kp = 17.5; Ti = 4 and Td = 2.
c) The PID controller gains obtained by the tuning method are worth: Kp = 10.5; Ti = 4 and Td = 1.
d) The PID controller gains obtained by the tuning method are worth: Kp = 10.5; Ti = 4 and Td = 2.
e) The PID controller gains obtained by the tuning method are worth: Kp = 17.5; Ti = 2 and Td = 0.5.
