Q. 161) State space analysis is applicable even if the initial conditions are

(A) zero

(B) non-zero

(D) not equal

View Answer Discuss Share

Correct answer:
Option (B) - non-zero

Explanation:

 state space analysis is the analysis different from the transfer function approach as it has state variables and state vectors used for the analysis and can be used even if initial conditions are non-zero.

Q. 162) Conventional control theory is applicable to              systems

(A) siso

(B) mimo

(D) non-linear

View Answer Discuss Share

Correct answer:
Option (A) - siso

Explanation:

 the major advantage of state space analysis is that it can be applied to mimo systems also while the conventional control theory that is transfer function approach is applicable to the siso systems only.

Q. 163) Insertion of negative feedback in control system affects:

(A) the transient response to vanish uniformly

(B) the transient response to decay very fast

(D) the transient response decays at slow rate

View Answer Discuss Share

Correct answer:
Option (B) - the transient response to decay very fast

Explanation:

 feedback can be positive or negative but practically positive feedback is not used as it causes oscillations in the system with more gain and hence negative feedback is use which causes speed of response to increase.
