A Robust, Efficient Predictive Safety Filter

no code implementations14 Nov 2023 Wenceslao Shaw Cortez, Jan Drgona, Draguna Vrabie, Mahantesh Halappanavar

In this paper, we propose a novel predictive safety filter that is robust to bounded perturbations and is implemented in an even-triggered fashion to reduce online computation.

Physics-Informed Machine Learning for Modeling and Control of Dynamical Systems

no code implementations24 Jun 2023 Truong X. Nghiem, Ján Drgoňa, Colin Jones, Zoltan Nagy, Roland Schwan, Biswadip Dey, Ankush Chakrabarty, Stefano Di Cairano, Joel A. Paulson, Andrea Carron, Melanie N. Zeilinger, Wenceslao Shaw Cortez, Draguna L. Vrabie

Specifically, the paper covers an overview of the theory, fundamental concepts and methods, tools, and applications on topics of: 1) physics-informed learning for system identification; 2) physics-informed learning for control; 3) analysis and verification of PIML models; and 4) physics-informed digital twins.

Domain-aware Control-oriented Neural Models for Autonomous Underwater Vehicles

no code implementations15 Aug 2022 Wenceslao Shaw Cortez, Soumya Vasisht, Aaron Tuor, Ján Drgoňa, Draguna Vrabie

Conventional physics-based modeling is a time-consuming bottleneck in control design for complex nonlinear systems like autonomous underwater vehicles (AUVs).

Differentiable Predictive Control with Safety Guarantees: A Control Barrier Function Approach

1 code implementation3 Aug 2022 Wenceslao Shaw Cortez, Jan Drgona, Aaron Tuor, Mahantesh Halappanavar, Draguna Vrabie

We develop a novel form of differentiable predictive control (DPC) with safety and robustness guarantees based on control barrier functions.

High-order Barrier Functions: Robustness, Safety and Performance-Critical Control

no code implementations31 Mar 2021 Xiao Tan, Wenceslao Shaw Cortez, Dimos V. Dimarogonas

Furthermore, the proposed formulation accounts for "performance-critical" control: it guarantees that a subset of the forward invariant set will admit any existing, bounded control law, while still ensuring forward invariance of the set.

Safe-by-Design Control for Euler-Lagrange Systems

1 code implementation8 Sep 2020 Wenceslao Shaw Cortez, Dimos V. Dimarogonas

The proposed approach consists of a sampled-data controller and an algorithm for barrier function construction to enforce safety (i. e satisfy position and velocity constraints).

On Compatibility and Region of Attraction for Safe, Stabilizing Control Laws

no code implementations27 Aug 2020 Wenceslao Shaw Cortez, Dimos V. Dimarogonas

A novel control method is proposed to ensure compatibility of safe, stabilizing control laws, i. e., simultaneous satisfaction of asymptotic stability and constraint satisfaction for nonlinear affine systems.
