Which of the following option is correct?
The root locus is the path of the roots of the characteristic equation traced out in the splane
Number of intersection of the asymptotes of the complete root loci is
The openloop transfer function of a unity feedback control system is given by:
The centroid and the angle of root locus asymptotes are respectively
Consider the loop transfer function K(s + 6) / (s + 3)(s +5 ) In the root locus diagram the centroid will be located at:
Assertion (A): Root locus is a graphical method in which roots of the characteristic equation are plotted in splane for the different value of parameter.
Reason (R): The locus of the roots of the characteristic equation when gain is varied from zero to infinity is called root locus.
Assertion ( A ) : An addition of real pole at s =  p_{0} in the transfer function G(s)H(s) of a control system results in the increase of stability margin.
Reason ( R ) : An addition of real pole at s =  p_{0} in the transfer function G(s)H(s) will make the resultant root loci bend towards the right.
The openloop transfer function of a closed loop control system is given as:
Which of the following statements is correct about the root locus of the above system?
The root locus of s(s  1) + K(s + 1) = 0 is a circle. The coordinates of the centre and the radius (in units) of this circle are respectively
What is the openloop transfer function of a unity feedback control system having root locus shown in the following figure?
A control system has G(s)H(s) (0 < K < ∞). The number of breakaway point in the root locus diagram is/are
