Physics–Guided Neural Networks for Feedforward Control: From Consistent Identification to Feedforward Controller Design

2022 IEEE 61st Conference on Decision and Control (CDC), 2022
Model-based feedforward control improves tracking performance of motion systems, provided that the model describing the inverse dynamics is of sufficient accuracy. Model sets, such as neural networks (NNs) and physics-guided neural networks (PGNNs) are typically used as flexible parametrizations that enable accurate identification of the inverse system

The engineering principles of combining a transcriptional incoherent feedforward loop with negative feedback

Journal of Biological Engineering, 2019
Background Regulation of gene expression is of paramount importance in all living systems. In the past two decades, it has been discovered that certain motifs, such as the feedforward motif, are overrepresented in gene regulatory circuits.
