Feedback Control For Computer Systems — Trusted

The primary objective of a feedback loop is to minimize the —the difference between a desired state ( Setpoint ) and the actual state ( Measured Output ). Setpoint (

): The target value (e.g., a 95% cache hit rate or 200ms latency). Controller ( Feedback Control for Computer Systems

The controller is the most common algorithm used to close the feedback loop. Feedback Control for Computer Systems [Book] - O'Reilly The primary objective of a feedback loop is
