Question

In this activity, you will compare closed-loop and open-loop control systems.

Background/Scenario

An open-loop control system does not monitor the output in order to determine what adjustments to make to

the input. For example, when using a clothes dryer you might set the timer on the dryer to run the drying cycle

for one hour. At the end of the hour, the dryer will stop. The level of dryness of the clothes will vary depending

upon their level of wetness at the beginning of the cycle.

In a closed-loop control system, the output is measured to determine whether it is the desired output and

adjust the input as appropriate. For example, if the clothes dryer is equipped with moisture sensors, the input

may be a level of dryness that adjusts the cycle by extending the drying time until the sensors indicate the

clothes are dried to a desired level.

Compare the systems listed in the table and determine if they are closed-loop or open-loop control systems.

Briefly explain your selections in the space provided.

Systems
Open/Closed Loop
Explain Your Answer
Clothes dryer with moisture sensor
Closed
The moisture sensors provide measured
output that is compared to a reference for
desired dryness. The controller will extend
the drying cycle until the input and output are
equal.
Light switch to turn on the light
Thermostat to keep a constant
temperature
Volume on a radio
Vehicle ignition switch
Ceiling fan
Clothes washing machine with
water level sensor
From the Open Loop systems, select one and describe how you might make it a Closed Loop system:
