Chapter 24, Problem 1SA
Describe the difference between an open- and a closed-loop operation.
Expert Solution & Answer

To determine
The difference between an open- and a closed-loop operation.
Answer to Problem 1SA
Closed-loop operations work on the principle of feedback. The output from the current operation is used to modify the input for the next operation. The open-loop operation works only on the input. There is no feedback for this open-loop operations.
Explanation of Solution
Some of the significant differences between an open- and a closed-loop operation are as follows:
Closed-loop operation | Open-loop operation |
Its basis is the output of the current operation. The feedback from the current output is used to modify the input. | Does not have any feedback system. It completely works on the input. |
Less stable. | Mostly stables. |
Overall cost is high. | Overall cost is low. |
Easy to calibrate. | Difficult to calibrate. |
Examples are refrigerator, Air conditioner, toaster, etc. | Examples are automatic washing machine, Traffic light, TV remote, etc. |
The structure of closed-loop operations are complex and so they are difficult to be implemented. | The structure of open-loop operations are simple and so they are easy to be implemented. |
Conclusion:
Closed-loop operation works on the feedback i.e. its basis is the output whereas open-loop operation is completely based on the input.
