Feedback Control For Computer Systems < PROVEN | 2025 >

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 algorithm that calculates what change to apply based on the error. Control Input ( Feedback Control for Computer Systems

): The target value (e.g., a 95% cache hit rate or 200ms latency). Controller ( The primary objective of a feedback loop is
