The control system is a set of the device which manages and directs the behavior of devices/systems to obtain the desired output.

Given below are the most important ** Control system MCQ Questions**.

## Laplace transform transforms

Laplace transform transforms:

- Time domain to s domain
- s domain to time domain
- One time to other time domain
- One s to other s domain

Correct answer: 1. Time domain to s domain

## Laplace transformer of e^-at

Laplace transformer of e^-at

- 1/s-a
- 1/s
- 1/a
- 1/s+a

Correct answer: 4. 1/s+a

## The type of transfer function denotes

The type of transfer function denotes:

- Number of poles at origin
- Number of zeros at origin
- Number of poles at infinity
- Number of zeros at infinity

Correct answer: 1. Number of poles at origin

## The position control is

The position control is:

- Process control
- Fussy system
- Regulation control
- Servomechanism

Correct answer: 4. Servomechanism

## The transient response of a system having feedback control

The transient response of a system having feedback control:

- Increases with time
- Decays with time
- Remains constant with time
- First increases then decay

Correct answer: 2. Decays with time

## Meaning of Feedback in Control Systems

In control systems the feedback means:

- Feeding output signal of one device to the input of the other device
- Feeding output signal of one device to the input of the two others device
- Return of a fraction of the output signal to the input of the same device
- None of these

Correct answer: 3. Return of a fraction of the output signal to the input of the same device

Effect of feedback on control systems is to reduce sensitivity of variations and system transient response control.
