Progress in gravitational-wave astronomy depends upon having sensitive detectors with good data quality. Since the end of the LIGO-Virgo-KAGRA third Observing run in March 2020, detector-characterization efforts have lead to increased sensitivity of

Constructive Safety-Critical Control: Synthesizing Control Barrier Functions for Partially Feedback Linearizable Systems

Autor: Cohen, Max H., Cosner, Ryan K., Ames, Aaron D.

Publikováno v: IEEE Control Systems Letters, 2024

Certifying the safety of nonlinear systems, through the lens of set invariance and control barrier functions (CBFs), offers a powerful method for controller synthesis, provided a CBF can be constructed. This paper draws connections between partial fe

A Constructive Method for Designing Safe Multirate Controllers for Differentially-Flat Systems

Autor: Agrawal, Devansh R., Parwana, Hardik, Cosner, Ryan K., Rosolia, Ugo, Ames, Aaron D., Panagou, Dimitra

Publikováno v: IEEE Control Systems Letters, Vol 6, Page 2138--2143, 2021

We present a multi-rate control architecture that leverages fundamental properties of differential flatness to synthesize controllers for safety-critical nonlinear dynamical systems. We propose a two-layer architecture, where the high-level generates

Bounding Stochastic Safety: Leveraging Freedman's Inequality with Discrete-Time Control Barrier Functions

Autor: Cosner, Ryan K., Culbertson, Preston, Ames, Aaron D.

When deployed in the real world, safe control methods must be robust to unstructured uncertainties such as modeling error and external disturbances. Typical robust safety methods achieve their guarantees by always assuming that the worst-case disturb
