Question 45
CHMCQ2 marksNeeds review
Level (
) in a steam boiler is controlled by manipulating the flow rate (
) of the make-up (fresh) water using a proportional (P) controller. The transfer function between the output and the manipulated input is
. The measurement and valve transfer functions are both equal to 1. A process engineer wants to tune the controller so that the closed-loop response gives decaying oscillations under servo mode. Which one of the following is the CORRECT value of the controller gain to be used by the engineer?Your answerChoose one option.
