What is the primary function of feedback control within a CPS Node?

The primary function of feedback control within a Cyber-Physical System (CPS) Node is to continuously monitor and adjust performance. Feedback control mechanisms are essential in ensuring that a system operates within desired parameters by observing the system's current state and making necessary adjustments based on that information.

In the context of a CPS Node, this active monitoring allows for dynamic response to changes in the environment or system conditions, effectively maintaining optimal performance. For instance, if a sensor detects that a component is operating outside its ideal temperature range, the feedback control would initiate a response to adjust cooling mechanisms, ensuring the system stays within operational limits.

This continuous monitoring and adjustment enhance the resilience and efficiency of a CPS, allowing it to adapt to varying scenarios in real-time. It is a fundamental part of maintaining system stability and achieving desired outcomes in both performance and energy utilization, as it enables proactive management rather than reactive measures. As a result, the feedback control function is integral to the success of CPS design and operation.
