Control Systems - GATE practice papers - Electronics & Communication for Q. 504
Q. Consider the statements given below:
A. Beginning of root locus with an open-loop pole at k = 0
B. Location of root locus about the real axis
C. Determination of the branches of root
D. Estimation of an angle of asymptote
E. Monitors the liability for the existence of real axis
F. Termination of root locus either on open-loop zero or at infinity
Which is the correct chronological order of sequential steps obligatory for the construction of root loci? (Marks : 02)- Published on 19 Oct 15a. A, D, E,B,C, F
b. A, B, C, D, E, F
c. B, A, F, C, E, D
d. B, F, A, D, E, C
ANSWER: B, A, F, C, E, D
Root locus is a graphical mechanism which is concerned to the plotting of roots of the characteristic equation in s-plane for several parameter values. It is mandatory to determine the root locus properly in proper sequential steps specified in option (c) so as to estimate the presence or location of any point on it by verifying the roots of characteristic equation with the assistance of angle and magnitude criteria.
