Nichol's chart deals with __________________?
Correct answer: A. Closed loop values vs. open loop values
- A. Closed loop values vs. open loop values
- B. A.R. vs. phase lag of second order
- C. A.R. vs. phase lag of first order
- D. Frequency response values of controllers
Explanation
A Nichols chart relates open-loop gain and phase to the resulting closed-loop performance, with closed-loop magnitude contours superimposed on the open-loop plot. Thus it is used to connect open-loop and closed-loop values.
