Difference at any instant between the value of the controlled variable and the set point is called the__________________?
Correct answer: B. Deviation
- A. Derivative time
- B. Deviation
- C. Error ratio
- D. Differential gap
Explanation
Deviation is the instantaneous difference between the set point and the controlled variable, with its sign depending on the convention used. Derivative time is a controller parameter, not the difference itself.
