Identification of Nonlinear Acyclic Networks in Continuous Time from Nonzero Initial Conditions and Full Excitations
Ramachandran Anantharaman, Renato Vizuete, Julien M. Hendrickx +1
This paper addresses the identifiability and identification of nonlinear acyclic networks in continuous time when the dynamics are located on the edges and all the nodes are excite…
Data-Driven Modeling of Photosynthesis Regulation Under Oscillating Light Condition - Part I: In-Silico Exploration
Christian Portilla, Arviandy G Aribowo, Ramachandran Anantharaman +2
This paper explores the application of data-driven system identification techniques in the frequency domain to obtain simplified, control-oriented models of photosynthesis regulati…
Hierarchical Decentralized Stochastic Control for Cyber-Physical Systems
Kesav Kaza, Ramachandran Anantharaman, Rahul Meshram
This paper introduces a two-timescale hierarchical decentralized control architecture for Cyber-Physical Systems (CPS). The system consists of a global controller (GC), and N local…
Estimation of Heat Transfer Coefficient in Heat Exchangers from closed-loop data using Neural Networks
Ramachandran Anantharaman, Carlos Gonzalez Rojas, Luna Artemis van Leeuwen +1
Heat exchangers (HEXs) play a central role in process industries for thermal energy transfer. Fouling, the gradual accumulation of solids on heat transfer surfaces, causes a time-v…
Koopman operator based identification of nonlinear networks
Ramachandran Anantharaman, Alexandre Mauroy
In this work, we develop a method to identify continuous-time nonlinear networked dynamics via the Koopman operator framework. The proposed technique consists of two steps: the fir…
Dynamic Mode Decomposition with Non-uniform Sampling
Ramachandran Anantharaman, Alexandre Mauroy
Dynamic Mode Decomposition (DMD) and its extensions (EDMD) have been at the forefront of data-based approaches to Koopman operators. Most (E)DMD algorithms assume that the entire s…
On Linear Representation, Complexity and Inversion of maps over finite fields
Ramachandran Anantharaman, Virendra Sule
This paper defines a linear representation for nonlinear maps where is a finite field, in terms of matrices over .…
