A Control Barrier Function Composition Approach for Multi-Agent Systems in Marine Applications

no code implementations21 Mar 2024 Yujia Yang, Chris Manzie, Ye Pu

The agents within a multi-agent system (MAS) operating in marine environments often need to utilize task payloads and avoid collisions in coordination, necessitating adherence to a set of relative-pose constraints, which may include field-of-view, line-of-sight, collision-avoidance, and range constraints.

Sub-Optimal Moving Horizon Estimation in Feedback Control of Linear Constrained Systems

no code implementations13 Apr 2023 Yujia Yang, Chris Manzie, Ye Pu

Moving horizon estimation (MHE) offers benefits relative to other estimation approaches by its ability to explicitly handle constraints, but suffers increased computation cost.

Real-Time Distributed Model Predictive Control with Limited Communication Data Rates

no code implementations26 Aug 2022 Yujia Yang, Ye Wang, Chris Manzie, Ye Pu

The cyclic-small-gain theorem is used to derive sufficient conditions on the quantization parameters for guaranteeing the stability of the system under a limited data rate.

Data-driven Predictive Tracking Control based on Koopman Operators

1 code implementation25 Aug 2022 Ye Wang, Yujia Yang, Ye Pu, Chris Manzie

Constraint handling during tracking operations is at the core of many real-world control implementations and is well understood when dynamic models of the underlying system exist, yet becomes more challenging when data-driven models are used to describe the nonlinear system at hand.

On-chip sampling of optical fields with attosecond resolution

1 code implementation13 Sep 2020 Mina R. Bionta, Felix Ritzkowsky, Marco Turchetti, Yujia Yang, Dario Cattozzo Mor, William P. Putnam, Franz X. Kärtner, Karl K. Berggren, Phillip D. Keathley

We demonstrated our devices by sampling the electric field of a ~5 fJ, broadband near-infrared ultrafast laser pulse using a ~50 pJ near-infrared driving pulse.
