## Definition
**Control systems** regulate processes by comparing observed state with a goal or reference condition and applying corrective action.
## Corpus Context
Control becomes governance when the regulated process contains persons or allocates consequential opportunities. [[wiki/Surveillance|Surveillance]] supplies state information, [[wiki/Behavioral Modification|behavioral modification]] supplies actuation and [[wiki/Information Asymmetry|information asymmetry]] determines whether the subject can inspect the feedback or contest the system's representation of error.
