Q.1
A lead compensator
  • Speeds up the transient response
  • Increases the stability margin
  • Increases the stability margin and speeds up the transient-response.
  • None of the above
Q.2
Lag compensation permits a high gain at low frequencies.
  • True
  • False
Q.3
The complicated shapes in the polar plots are only due to time constants in the numerator of transfer functions.
  • True
  • False
Q.4
Which of the following features is not associated with Nichols chart?
  • (0 dB, -180°) point on Nichols chart represent critical Point (-1, 0)
  • It is symmetric about -180°
  • M loci are centred about (0 dB, -180°) point
  • The frequency at intersection of G(j?) locus and M = +3 dB locus gives bandwidth of closed loop system
Q.5
A lag compensator
  • Speeds up the transient response of the system
  • Improves steady state behavior of the system
  • Improves steady state behavior and speeds up the transient response of the system
  • Improves steady state behavior and preserves the transient response of the system
Q.6
In root locus analysis the breakaway and break in points
  • lie on the real axis
  • Either lie on the real axis or occur in complex conjugate pairs
  • Always occur in complex conjugate pairs
  • None of the above
