Control Systems .
A composite R-C network yielded the following transfer function when calculated from its components:
$$T\left( s \right) = \frac{{C\left( s \right)}}{{R\left( s \right)}} = \frac{{1 + 21s + 20{s^2}}}{{1 + 11s + 10{s^2}}}$$
This network can be used as which one of the following?
For a state space representation of a system \[{\rm{A}} = \left[ {\begin{array}{*{20}{c}}
0&1\\
{ - 3}&{ - 2}
\end{array}} \right],\,{\rm{B}} = \left[ \begin{array}{l}
0\\
1
\end{array} \right]\] and C = [1 2] . Then transfer function of system would be:
Consider the following statements regarding the asymptotic Bode plots used for frequency response analysis:
1. The deviation of the actual magnitude response for a zero on real axis is 3 dB at the corner frequency.
2. The phase angle for a pair of complex conjugate poles at undamped frequency depends upon the value of damping ratio.
Which of the statements given above is/are correct?
Consider a unity feedback system having a transfer function $$G\left( s \right) = \frac{{100}}{{s\left( {0.1s + 1} \right)}}$$ is subjected to ramp input. The steady-state error is:
A unity feedback system has $$G\left( s \right) = \frac{{K\left( {2s + 1} \right)}}{{s\left( {4s + 1} \right){{\left( {s + 1} \right)}^2}}}$$
What is the value of K if the steady-state value of error is to be less than 0.1 when an input r(t) = 1 + 5t is applied?
If the output of the system at steady state doesn't agree with the input, then the system is said to have . . . . . . . . which determines the . . . . . . . . of the system.
