Control-relevant neural networks for feedforward control with preview: Applied to an industrial flatbed printer

The performance of feedforward control depends strongly on its ability to compensate for reproducible disturbances. The aim of this paper is to develop a systematic framework for artificial neural networks (ANN) for feedforward control. The method involves three aspects: a new criterion that emphasizes the closed -loop control objective, inclusion of preview to deal with delays and non -minimum phase dynamics, and enabling the use of an iterative learning algorithm to generate training data in view of addressing generalization errors. The approach is illustrated through simulations and experiments on an industrial flatbed printer. (c) 2024 The Author(s). Published by Elsevier Ltd.
