Learning Higher Order DC-DC Converter Control from Inversion
Kamakshi Tatkare, Ufuk Topcu, Brian Johnson
Control design for high-order converters with nonlinear dynamics is generally difficult. Nonlinear controls introduce formidable model complexity whereas linear controls suffer fro…
Flatness-based Neural Network Control of DC-DC Converters
Kamakshi Tatkare, Ufuk Topcu, Brian Johnson
In this work, we present a simple method to engineer a small neural network to control power converters. Learning-based methods have emerged as a promising approach for power conve…
Cislunar Pursuit-Evasion Game on Periodic and Quasi-Periodic Orbits
Quentin Rommel, Filippos Fotiadis, Cade Armstrong +2
Cislunar spacecraft operate in nonlinear and unstable environments that make defensive maneuver planning difficult. We formulate cislunar spacecraft pursuit and evasion as a zero-s…
Secure Coordination for Vertiport Sequencing in Advanced Air Mobility
Jaehan Im, Filippos Fotiadis, Ufuk Topcu +1
Advanced air mobility operations will require reliable coordination mechanisms for managing dense traffic near vertiports. However, sequencing decisions may become vulnerable when…
Linear-Quadratic Gaussian Games with Distributed Sparse Estimation
Tianyu Qiu, Filippos Fotiadis, Xinjie Liu +5
Linear-quadratic Gaussian games provide a framework for modeling strategic interactions in multi-agent systems, where agents must estimate system states from noisy observations whi…
Noncooperative Virtual Queue Coordination via Uncertainty-Aware Correlated Equilibria
Jaehan Im, David Fridovich-Keil, Ufuk Topcu
Collaborative virtual queueing has been proposed as a mechanism to mitigate airport surface congestion while preserving airline autonomy over aircraft-level pushback decisions. A c…
