Title :
Towards an Abstract Internal Model Principle
Abstract :
In the setting of abstract automata, it is shown that a feedback regulator must incorporate a dynamic model of the exosystem ("outside world") to which the regulator is designed to respond. The result is based on general lattice-theoretic definitions of the concepts of feedback and observability.
