Learning Control-Affine Reduced-Order Models via Autoencoders

arXiv:2606.05045v1 Announce Type: cross Abstract: We present in this paper a framework for the identification of control-affine reduced-order models (ROMs). The proposed method utilizes autoencoders (AEs) to transform the high-dimensional states, and potentially the high-dimensional inputs, into reduced latent ones suitable for control-affine state-space dynamics. This is achieved by simultaneous training of the AE and the state-space model. In addition, we extend the discrete ROM formulation to a sequence-based model, which processes state and input histories to improve prediction accuracy wh

Why this matters
Why now

The proliferation of complex high-dimensional systems across engineering and scientific domains necessitates more efficient model reduction techniques to enable real-time control and simulation.

Why it’s important

This development offers a novel approach to create accurate, control-affine reduced-order models, which is crucial for advancing AI's application in systems requiring high computational efficiency and real-time decision-making.

What changes

The ability to simultaneously train autoencoders with state-space dynamics for control-affine systems provides a more robust and integrated method for model reduction, potentially leading to widespread adoption in control systems.
