Definitionv1DF-450
Shared variable
a variable that serves as the output of one feedback loop and becomes the input of another feedback loop, creating coupling between loops that affects system behavior through their combined responses
Why This Is a Definition
This definition precisely captures what makes a variable 'shared' in multi-loop systems by specifying its functional role as a connector between loops. It explains how shared variables create coupling effects that determine system behavior through the interaction of different loop responses.
