Primes¶
- Good Regulator Theorem
- In control engineering and cybernetics, the internal-model principle is essentially Conant–Ashby for linear systems: a controller can asymptotically reject a class of disturbances only if its dynamics include a copy of the disturbance generator, and the optimal state estimator is a model of the plant.
This sourceStates the internal-model principle: a controller achieves asymptotic disturbance rejection only if its feedback loop contains a model (a reduplicated copy of the modes) of the exosystem generating the disturbance/reference — e.g., an integrator models a constant disturbance.

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
