Correct answer: A. Deviation
- A. Deviation
- B. Derivative time
- 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.
