Control & regulation theory (wiki)

Parent: cybernetics

Established regulation/control results:

• ashby — variety, requisite variety, ultrastability.
• good-regulator-theorem — every good regulator must be a model of its system.
• ramadge-wonham-supervisory-control — supervisory control of discrete-event systems; disable-not-force, supC(K).
• stages-and-gates — reference material on staged processes and task decomposition.
• git-as-agent-trust-substrate — git + deterministic lint as the trust substrate between untrusted agents: content-addressing binds what was audited to what ships (promoted 2026-07-18)
