Closed-Loop vs Open-Loop Systems

The video tutorial covers the principles of open and closed loop systems, using examples like clothes dryers and microwaves to illustrate the differences. It provides instructions for modifying a test bed to create a closed loop system using a limit switch. The tutorial also includes programming tasks to create both open and closed loop systems, encouraging students to work together and seek support if needed.

What is a characteristic of an open-loop system?

• It adjusts based on input.

• It requires manual intervention.

• It provides feedback.

• It operates without feedback.

Which of the following is an example of an open-loop system?

• A microwave oven

• A clothes dryer with moisture sensors

• A thermostat-controlled heater

• A modern washing machine

How does a closed-loop system differ from an open-loop system?

• It does not require any input.

• It operates faster.

• It uses feedback to adjust its operation.

• It is less efficient.

What role do moisture sensors play in a modern clothes dryer?

• They make the dryer quieter.

• They reduce the energy consumption.

• They increase the drying time.

• They provide feedback to adjust drying time.

What is the purpose of adding a limit switch to the test bed?

• To provide feedback for a closed-loop system

• To create an open-loop system

• To increase the speed of the motor

• To reduce the noise of the motor

In the test bed modification, what happens when the limit switch is pressed?

• The motor changes direction.

• The motor stops completely.

• The motor slows down.

• The motor speeds up.

What is the first step in programming the motor for the open-loop system?

• Connect the motor to a power source.

• Add a limit switch.

• Write a program to oscillate the motor.

• Test the motor with feedback.

How many times should the motor oscillate in the open-loop program?

• 10 times

• 15 times

• 20 times

• 25 times

What should students do if they have questions during the exercise?

• Wait until the next class.

• Search online for answers.

• Email the teacher immediately.

• Discuss with other groups or the substitute.

What is the final instruction given by the teacher?

• Prepare for a test.

• Have a good day.

• Submit the assignment online.

• Review the video again.
