Questions and Answers

Which of the following statements is true about feedback in control systems?

Feedback can reduce the effect of noise and disturbance on system performance (correct)

Feedback is always harmful if not properly applied

Feedback has no effect on system performance

Feedback always improves stability.

What is the ideal sensitivity of the system gain in a feedback system?

The sensitivity should be high for both input commands and parameter variations.

The sensitivity should be sensitive to input commands but insensitive to parameter variations. (correct)

The sensitivity should be low for both input commands and parameter variations.

The location of the parameter does not affect the sensitivity.

What is the purpose of control systems?

To be insensitive to input commands.

To be designed without feedback loops.

To control the input and output of a system. (correct)

To manage or regulate the behavior of other devices using control loops.

Study Notes

Control system is a system that controls the output by varying the input.
Feedback in control systems can improve stability or be harmful if not properly applied.
Feedback can reduce the effect of noise and disturbance on system performance.
The sensitivity of the system gain in a feedback system depends on the location of the parameter.
A good control system is sensitive to input commands but insensitive to parameter variations.
It is not good for a control system to be insensitive to input commands.
Control systems can be positive or negative feedback systems.
Control systems do not manage or regulate the behavior of other devices using control loops.
The input and output are controlled in a control system.
Control systems are designed to regulate and control processes.
