The industrial controller having the best steady-state accuracy is:
A. A derivative controller
B. An integral controller
C. A rate feedback controller
D. A proportional controller
Answer:A
The industrial controller having the best steady-state accuracy is:
A. A derivative controller B. An integral controller C. A rate feedback controller D. A proportional controller
Explanation: The best steady state accuracy is of derivative controller and this is due to the fact that derivative controller is only affected by the steady state response not the transient response.
