Differentiate between open and closed loops in control systems.

Differentiation should include

• defining open-loop system (i.e., a system without a feedback mechanism) (e.g., washing machine, irrigation sprinkler system, robot driving from joystick input)
• defining closed-loop system (i.e., a system with a feedback mechanism) (e.g., aquarium pump, hot water heating system, computer mouse, joystick on a video game, robot driving toward a light)
• describing why one system would be preferred over the other.

Process/Skill Questions:

• What is an input?
• What is a process?
• What is an output?
• How can feedback change a system?
• What are the differences between open-loop systems and closed-loop systems?
• What are some examples of open-loop and closed-loop systems?
• What are the strengths of a closed-loop system?
• How are open-loop systems used in everyday life?
