What is a notable disadvantage of closed loop systems?

1. They are less accurate

2. More expensive

3. Less effective

4. More difficult to operate

The correct answer is: More expensive

Closed loop systems are designed to continuously monitor their output and make adjustments based on feedback. This feedback mechanism allows for higher accuracy and precision in controlling the system. However, one notable disadvantage of closed loop systems is that they tend to be more expensive than their open loop counterparts. The reasons for the increased cost include the need for additional sensors to monitor output, more complex control algorithms, and greater processing requirements. These factors contribute not only to higher initial setup and material costs but also potentially to increased maintenance costs due to the complexity of the system. While closed loop systems provide enhanced performance and reliability, the price tag associated with them can make them less accessible for certain applications, especially where budgets are tight.
