feedback-control is a human-made control architecture in which a system's output is continuously measured, compared to a desired reference value, and the resulting error drives corrective action to reduce the difference. Parameters: (1) forward path — the plant or process being controlled; (2) feedback path — the sensor and signal conditioning that measures the output; (3) controller — the element that computes the error signal and generates the corrective command; (4) feedback sign — negative (stabilizing, error-reducing) or positive (regenerative, error-amplifying). Persistence: through design practice across mechanical, electrical, and software systems, formalized in control theory and embedded in automation, instrumentation, and servo mechanisms.

Definition
Why it is in scope
A human-made control architecture in which a system's output is measured and compared to a desired reference, with the error signal used to drive corrective adjustment; built to persist through engineering practice from mechanical governors to modern digital controllers.

Feedback-control uses signal as the feedback variable to regulate operation; remove signal and the control loop stops operating.
- cmru8g36700asr671i0fmsm35INSTANCE_OF →
Feedback control is a specific kind of process where a system's output is fed back to adjust its input. The note pins the sense: a process is any systematic series of operations, and feedback control is that series configured with a feedback loop. Law 9: specific→general. Process is the nearest accepted kind.

- phase-locked-loop← INSTANCE_OF
A phase-locked-loop is a specific kind of feedback-control system: it measures output phase, compares it to a reference, and adjusts a VCO via the error signal. The feedback loop (phase detector → loop filter → VCO) is a classic negative-feedback architecture. Nearest kind: feedback-control.
