Questions and Answers
What is the difference between closed loop control and open loop control?
Closed loop control uses feedback or sensors to automatically regulate a system without human interaction, while open loop control does not have a feedback system and requires manual adjustment.
What is an example of a mechanical closed loop system?
Bimetallic temperature switches or self-regulating valves are examples of mechanical closed loop systems.
Why are closed loop control systems more desirable than open loop systems?
Closed loop control systems are more desirable because they are sensitive to changes and can maintain a desired state or set point, while open loop systems do not have the ability to automatically adjust and may result in errors or inconsistencies.
Study Notes

- Closed loop systems are more desirable than open loop systems
- Most modern closed loop systems are electronically controlled
- Complex closed loop systems can use sensors for multiple inputs and outputs
- Old or low-cost systems may use a mechanical closed loop system
- Examples of mechanical closed loop systems are bimetallic temperature switches or self-regulating valves
- Closed loop control systems are sensitive to changes and maintain a desired state or set point.
