We are designing an electrical system in which the two primary sub-systems work in a manner such that the first one controls the power for the second one (and handles some primary tasks), and the second sub-system is then responsible for more advanced tasks.
Now, there is a common terminology that is used in similar systems:
master-slave architecture or relationship. However, in a master-slave relationship, the
master not only has the "control", it also has more "power" and do the more advanced tasks. In our case, the first system has "control", but is not "powerful" enough to do advanced tasks. That is, in our case, the first system is more of a "gatekeeper" rather than a "master".
What would be a proper terminology for such systems or relationships?
The question, while being asked for a specific case, is general and is asking about such relationships in general, and not necessarily engineering systems.
In case someone points out, I'm asking this here and not some Engineering forum, because we need a new term for it, which does not formally exist in engineering circles.
