Control theory is also used by databases (probably not as often as it should be). It's great for "self tuning" [1], for example tuning the various cache sizes a database has to maximize throughput under changing workload conditions. Its definitely worth spending the time to understand PID controllers if your an engineer working on databases.[1] https://www.vldb.org/conf/2006/p1081-storm.pdf

There's a lot of terrible things people do in ignorance of control theory while trying to come up with solutions in that space.
