The open loop transfer function of a unity feedback control system is given by
The breakaway point in its root locus will lie between
The characteristic equation of a closed loop control system is given by:
s^{2 }+ 2s +10 + K(s^{2} + 6s + 10) = 0
The angle of asymptotes for the root loci for K ≥ 0 are given by
The breakaway point in the root loci plot for the loop transfer function
Consider the following statements pertaining to root locus techniques:
1. RouthHurwitz criterion may be used to find the intersections of the root loci on the imaginary axis.
2. Breakaway points on the root loci of an equation corresponds to multipleorder roots of the equation.
3. The breakaway points on the root loci of 1 + KG(s) H(s) = 0 must satisfy
4. n root loci arrive or depart a breakaway point at 180/n degrees.
Which of these statements are correct?
Assertion (A): From the root sensitivity standpoint, a system should not be operated at the breakaway points.
Reason (R): The root sensitivity at the breakaway points is zero.
Consider the following statements:
1. All the rules and properties for the construction of root loci in the splane can be applied to the construction of root loci of discrete data system in the zplane without any modification.
2. The breakaway points of the root loci must always be on the real axis.
3. There is only, one intersection of the asymptotes of the complex root loci.
4. Adding a pole to Q(s)/P(s) has the general effect of pushing the root loci to the left, whereas adding a zero pushes the loci to the right.
Which of the above statements is/are not correct related to root locus technique in control system?
For the loop transfer function:
the angle of departure at s = j for K > 0 is
