7.8. Interfacing Actuators with Control Systems

Try these first

1. 1.

   What are the three key components of a control system?

   Hint

   Think about the functions they serve in automation.

2. 2.

   Define open-loop control.

   Hint

   Consider a device that runs without checking its output.

3. 3.

   What is a key feature of closed-loop control?

   • No feedback
   • Feedback used for adjustments
   • Only sometimes uses feedback

   Hint

   Think about how feedback affects performance.

4. 4.

   True or False: An example of open-loop control is a fan motor controlled by a switch.

   • True
   • False

   Hint

   Remember, open-loop means no feedback!

5. 5.

   Design an automated irrigation system utilizing closed-loop control principles.

   Hint

   Think about how plants signal their need for water.

6. 6.

   Explain how the principles of feedback can enhance the performance of a robotic arm in a manufacturing setting.

   Hint

   Consider how errors might arise without constant oversight.
