QUESTION: 1

A feedback control systems has the inherent capability that its parameter can be adjusted to alter both its transient and steady state responses.

Solution:

Answer: a

Explanation: Feedback’s inherent capability is that its parameter can be adjusted to alter both transient and steady state responses as together they are referred to as time responses.

QUESTION: 2

Transient response analysis is done for_________ systems.

Solution:

Answer: b

Explanation: In case the system happens to be unstable, we need not proceed with its transient response analysis.

QUESTION: 3

The input signals to control systems are not known fully ahead of time, the characteristics of control system which suddenly strain a control system are:

Solution:

Answer: d

Explanation: System dynamic behavior for analysis and design is therefore judged and compared under standard test signals.

QUESTION: 4

Standard test signals in control system are:

Solution:

Answer: d

Explanation: Standard test signals are impulse, ramp and unit step all of the above to test the dynamic behavior of the control system.

QUESTION: 5

The nature of transient response is revealed by ______________

Solution:

Answer: d.

Explanation: The nature is dependent on system poles not on the dynamic inputs.

QUESTION: 6

It is generally used to analyze the transient response to one of the standard test signals.

Solution:

Answer: a

Explanation: For analyzing transient response mainly step is used and also other signals mainly ramp and parabolic are not used for this analysis but they are used for steady state analysis.

QUESTION: 7

Step signal is the signal whose values is :

Solution:

Answer: d

Explanation: Step signal is the signal whose value varies from zero to level in zero time.

QUESTION: 8

Ramp input :

Solution:

Answer: c

Explanation: Ramp signal denotes constant velocity and also basic definition states that its value increases linearly with time.

QUESTION: 9

A perfect impulse has one value at zero time instant but otherwise zero elsewhere.

Solution:

Answer: b

Explanation: A perfect impulse signal has infinite value at zero but mathematically only a small pulse is taken with finite limits.

QUESTION: 10

To find system’s response by means of convolution integral ____________ of the system is used.

Solution:

Answer: d.

Explanation: Impulse response of a system is the inverse Laplace transfer function of its Laplace function.
