Open-loop system vs Closed-loop system
In control systems, there are two types of systems - open-loop and closed-loop.
Open-loop system:
- A system that does not have any feedback mechanism
- Input is given and output is obtained without any consideration of the output.
- Output is not monitored to see if it is achieving the desired output.
- Examples: Traffic light system, washing machine, toaster, etc.
Closed-loop system:
- A system that has a feedback mechanism
- Output is monitored and compared with the desired output and any error is corrected
- The system adjusts itself to achieve the desired output
- Examples: Temperature control system, speed control system, etc.
Traffic light system as an example of open-loop system:
- Traffic light system is an example of an open-loop system because it does not have any feedback mechanism.
- The traffic lights change based on a pre-programmed schedule and not based on the traffic on the road.
- The system does not adjust itself to the traffic conditions and does not correct any errors.
- The system does not monitor the traffic flow to see if the desired output is achieved.
Conclusion:
- Therefore, the correct answer to the question is option 'A' - Traffic light system is an example of an open-loop system.
