The main objective of drawing root locus plot is :
A. To obtain a clear picture about the open loop poles and zeroes of the system
B. To obtain a clear picture about the transient response of feedback system for various values of open loop gain K
C. To determine sufficient condition for the value of ‘K’ that will make the feedback system unstable
D. Both b and c
Answer:D
The main objective of drawing root locus plot is :
A. To obtain a clear picture about the open loop poles and zeroes of the system B. To obtain a clear picture about the transient response of feedback system for various values of open loop gain K C. To determine sufficient condition for the value of ‘K’ that will make the feedback system unstable D. Both b and c
Explanation: The main objective of drawing root locus plot is to obtain a clear picture about the transient response of feedback system for various values of open loop gain K and to determine sufficient condition for the value of ‘K’ that will make the feedback system unstable.
