A Robust, Efficient Predictive Safety Filter

1 code implementation14 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.

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.
