Nichol’s chart:
Which one of the following statements is correct?Nichol’s chart is useful for the detailed study of:
A system has fourteen poles and two zeros. Its high frequency asymptote in its magnitude plot having a slope of
Loop transfer function of a feedback system is \(G\left( s \right)H\left( s \right) = \frac{{s + 3}}{{{s^2}\left( {s - 3} \right)}}\;.\) Take the Nyquist contour in the clockwise direction. Then, the Nyquist plot of G(s) H(s) encircles \(- 1 + j0\)
In the Bode plot of a unity feedback control system, the value of phase angle of G (jω) is -90° at the gain cross over frequency of the Bode plot, the phase margin of the system is:
Consider two control systems with the following transfer functionsSystem 1: \(G\left( s \right) = \frac{1}{{3s + 1}}\) System 2: \(G\left( s \right) = \frac{1}{{s + 1}}\) Which of the following is true?
If the gain of an open loop system is doubled, the gain margin
For the transfer function, \(G\left( s \right) = \frac{{5\left( {s + 4} \right)}}{{s\left( {s + 0.25} \right)\left( {{s^2} + 10s + 25} \right)}}\), the values of the constant gain term and the highest corner frequency of the Bode plot respectively are:
Polar plot of sinusoidal transfer function is a plot of:
If the gain margin of a system in decibels is negative, the system is:
