AME 11 Q1

1 / 5

How does hysteresis improve the performance of an On-Off control system?

C) It allows the system to adjust output continuously.

B) It prevents rapid cycling by creating a dead zone between switching on and off.

D) It enables the system to predict and correct future errors.

A) It increases the switching frequency of the system.

2 / 5

In an On-Off control system, what happens when the controlled variable exceeds the set point?

D) The system remains inactive until the variable drops significantly.

A) The system modulates the output to gradually reduce the variable.

B) The system switches off the output to bring the variable back to the set point.

C) The system increases the output to correct the error.

3 / 5

What is the primary characteristic of a Discontinuous (On-Off) control system?

B) The output is either fully on or fully off, with no intermediate states.

D) The system provides proportional control based on the error magnitude.

A) The output is continuously variable.

C) The system adjusts output in small increments.

4 / 5

D) It consumes more energy than other types of control systems.

A) It requires complex programming to function.

B) It is unable to achieve precise control, leading to oscillations around the set point.

C) It is more expensive than proportional control systems.

5 / 5

B) Temperature control in a household thermostat.

D) Flow control in a proportional valve system.

C) Pressure regulation in a hydraulic system.

A) Speed control of a variable frequency drive.
