Abstract
We show that any asymptotic observer for a non-linear repeatable system on a differentiable manifold contains a full internal model of the plant as long as the observer is constructed on a state manifold that is a fibre bundle over the state manifold of the plant and observer trajectories are locally fibre-bounded. Examples of repeatable systems are controllable systems and kinematic systems. The result follows from an abstract, set-theoretic internal model principle that generalises the known results for classical LTI systems, behavioural systems, and systems described by injective co-generator signal modules (Oberst’s algebraic analysis approach to system theory). Most of the results in this talk were presented at the MTNS in 2022 and 2024.
