Question
can you explain the steps how you get the correct answer
15. The figure below on the left. labeled "Original" shows a root locus plot for a system t two open-loop zeros and two open-loop poles. Original Choice A Choice EB new new 0 The two plots on the right side have for the addition of one "new" open-loop pole and one "new" open-loop Among Choices A and B, one is a correct root locus plot; the other is incorrect. Which one is correct? the same open-loop poles and zeros as the original, except A. I know that Choice A is correct (Please be honest.) B. I know that Choice B is correct (Please be honest.) C. I'm not sure which is correct (Please be honest.)Explanation / Answer
The root locus of the originalsystem says that the locus lie of verge of instability.
in the root locus of figure A a compensator is added so that the locus is in the left half s-plane . that is the compensator ha pulled the locus in the stable region. so this choice is correct
in figure B the locus is on the right half s plane which indicated unstable configuration
normally we will design a compensator to make an unstable system stable by varying gain or location of pole or location of zero or combination of these
