Test: Transfer Functions - Question 1

Which of the following is not the feature of modern control system?

Detailed Solution for Test: Transfer Functions - Question 1

Explanation: For a good control system the speed of response and stability must be high and for the slow and sluggish response is not used and undesirable.

Test: Transfer Functions - Question 2

The output of the feedback control system must be a function of:

Detailed Solution for Test: Transfer Functions - Question 2

Explanation: Feedback control system has the property of reducing the error and that is by differencing the output with the desired output and as the equation of the output of the system is C=GR/1+GH.

Test: Transfer Functions - Question 3

The principles of homogeneity and super position are applied to ____

Detailed Solution for Test: Transfer Functions - Question 3

The principal of superposition and homogeneity are applied to linear time invariant (LTI) system only.

Test: Transfer Functions - Question 4

In continuous data systems:

Detailed Solution for Test: Transfer Functions - Question 4

Explanation: Continuous signals are the signals having values for the continuous time and if impulse response decays to zero as time approaches infinity, the system is stable.

Test: Transfer Functions - Question 5

A linear system at rest is subject to an input signal r(t)=1-e-t. The response of the system for t>0 is given by c(t)=1-e-2t. The transfer function of the system is: 

Detailed Solution for Test: Transfer Functions - Question 5

Explanation: c(t)=1-e-2t
R(s)=1/s-1/s+1
C(s)=1/s-1/s+2
Tf=2(s+1)/(s+2).

Test: Transfer Functions - Question 6

In regenerating the feedback, the transfer function is given by

Detailed Solution for Test: Transfer Functions - Question 6

Explanation: Regenerating feedback is positive feedback and it increases the infinitely and hence the speed of response of the system reduces.

Test: Transfer Functions - Question 7

Traffic light system is the example of:

Detailed Solution for Test: Transfer Functions - Question 7

The traffic lamp will glow according to the set timing and sequence and is time-dependent. The sequence and time are controlled by relays that work on the pre-programmed time. It does not depend upon the rush of the road.

Test: Transfer Functions - Question 8

A transfer function has two zeroes at infinity. Then the relation between the numerator(N) and the denominator degree(M) of the transfer function is:

Detailed Solution for Test: Transfer Functions - Question 8

Explanation: Zeroes at infinity implies two poles at origin hence the type of the system is two and degree of denominator is M=N+2.

Test: Transfer Functions - Question 9

When deriving the transfer function of a linear element

Detailed Solution for Test: Transfer Functions - Question 9

Explanation: When deriving the transfer function of a linear element only initial conditions are assumed to be zero, loading cannot be assumed to be zero.

Test: Transfer Functions - Question 10

If the initial conditions for a system are inherently zero, what does it physically mean?

Detailed Solution for Test: Transfer Functions - Question 10

Explanation: A system with zero initial condition is said to be at rest since there is no stored energy.
