Armenta, C. (author), Delprat, S. (author), Hawksley, B. (author), Negenborn, R.R. (author)This work proposes a controller design that integrates an Equivalent Consumption Minimization Strategy framework and a quasi-LPV framework. The proposed scheme allows exploiting the characteristics of both frameworks. Also, a proof of the input-state-stability (ISS) of the closed-loop is presented, expressed as linearmatrix-inequality conditions...journal article 2022

Karademir, C. (author), Alves Beirigo, B. (author), Negenborn, R.R. (author), Atasoy, B. (author)This study considers an integrated water- and land-based transportation (IWLT) system for waste collection. Research on the issue is motivated by increased heavy street movements that damage quay walls as well as congestion. We present a novel two-echelon vehicle routing problem with satellite synchronization based on a two-index formulation and...conference paper 2022

Alves Beirigo, B. (author), Negenborn, R.R. (author), Alonso Mora, J. (author), Schulte, F. (author)With the popularization of transportation network companies (TNCs) (e.g., Uber, Lyft) and the rise of autonomous vehicles (AVs), even major car manufacturers are increasingly considering themselves as autonomous mobility-on-demand (AMoD) providers rather than individual vehicle sellers. However, matching the convenience of owning a vehicle...journal article 2022
