Spectral Koopman-Hopf Formula for Reachability with Adversary
Sarang Sutavani, Umesh Vaidya
This paper develops a spectral Koopman-Hopf framework for adversarial reachability analysis of nonlinear systems. By lifting the nonlinear drift dynamics into Koopman eigenfunction…
A Data-Driven Koopman-Behavioral Distance for Nonlinear Dynamical Systems
Sarang Sutavani, Umesh Vaidya
Comparing nonlinear dynamical systems directly from trajectory data remains challenging because finite-horizon trajectory representations are generally coordinate dependent. Motiva…
SE(3) Koopman-MPC: Data-driven Learning and Control of Quadrotor UAVs
Sriram S. K. S. Narayanan, Duvan Tellez-Castro, Sarang Sutavani +1
In this paper, we propose a novel data-driven approach for learning and control of quadrotor UAVs based on the Koopman operator and extended dynamic mode decomposition (EDMD). Buil…
Koopman-based Policy Iteration for Robust Optimal Control
Alexander Krolicki, Sarang Sutavani, Umesh Vaidya
Classically, the optimal control problem in the presence of an adversary is formulated as a two-player zero-sum differential game or an control problem. The solution to…
