How would you verify if the system is functioning properly in a closed loop?

Verifying if a system is functioning properly in a closed loop primarily involves ensuring the feedback mechanisms are operating as intended. The feedback loop is a critical component in closed-loop systems as it provides the necessary data to the controller about the output, allowing it to make adjustments that maintain the desired performance.

When inspecting the feedback loop, you check the sensors that measure the output and the data being sent back to the controller. This process ensures that the system is accurately responding to the changes in conditions and maintaining control based on the feedback it receives. If the feedback loop is functioning correctly, it indicates that the controller can receive accurate measurements and make precise adjustments, thereby confirming the overall functioning of the system.

While checking voltage levels, using an oscilloscope, or monitoring pressure readings can provide valuable information about specific components or conditions within a system, they do not fully encompass the verification of the entire closed-loop process as effectively as inspecting the feedback loop does. The effectiveness of a closed-loop control system hinges on the proper functioning of this feedback mechanism, making it essential for overall system verification.
