With this as motivation, this paper presents a safety-critical control framework that leverages reduced order models to ensure safety on the full order dynamics-even when these models are subject to disturbances and bounded inputs (e.g., actuation limits). To handle input constraints, the backup set method is reformulated in the context of reduced order models, and conditions for the provably safe behavior of the full order system are derived. Then, the input-to-state safe backup set method is introduced to provide robustness against discrepancies between the reduced order model and the actual system. Finally, the proposed framework is demonstrated in high-fidelity simulation, where a quadrupedal robot is safely navigated around an obstacle with legged locomotion by the help of the unicycle model.}, year = {2023}, pages = {1414-1421}, orcid-numbers = {Molnár, Tamás Gábor/0000-0002-9379-7121} } @article{MTMT:34326699, title = {Connected Cruise and Traffic Control for Pairs of Connected Automated Vehicles}, url = {https://m2.mtmt.hu/api/publication/34326699}, author = {Guo, Sicong and Orosz, Gábor and Molnár, Tamás Gábor}, doi = {10.1109/TITS.2023.3285852}, journal-iso = {IEEE T INTELL TRANSP}, journal = {IEEE TRANSACTIONS ON INTELLIGENT TRANSPORTATION SYSTEMS}, volume = {24}, unique-id = {34326699}, issn = {1524-9050}, abstract = {This paper considers mixed traffic consisting of connected automated vehicles equipped with vehicle-to-everything (V2X) connectivity and human-driven vehicles. A control strategy is proposed for communicating pairs of connected automated vehicles, where the two vehicles regulate their longitudinal motion by responding to each other, and, at the same time, stabilize the human-driven traffic between them. Stability analysis is conducted to find stabilizing controllers, and simulations are used to show the efficacy of the proposed approach. The impact of the penetration of connectivity and automation on the string stability of traffic is quantified. It is shown that, even with moderate penetration, connected automated vehicle pairs executing the proposed controllers achieve significant benefits compared to when these vehicles are disconnected and controlled independently.}, year = {2023}, eissn = {1558-0016}, pages = {12648-12658}, orcid-numbers = {Molnár, Tamás Gábor/0000-0002-9379-7121} } @article{MTMT:34052516, title = {Safety-critical traffic control by connected automated vehicles}, url = {https://m2.mtmt.hu/api/publication/34052516}, author = {Zhao, Chenguang and Yu, Huan and Molnár, Tamás Gábor}, doi = {10.1016/j.trc.2023.104230}, journal-iso = {TRANSPORT RES C-EMER}, journal = {TRANSPORTATION RESEARCH PART C-EMERGING TECHNOLOGIES}, volume = {154}, unique-id = {34052516}, issn = {0968-090X}, year = {2023}, eissn = {1879-2359}, orcid-numbers = {Yu, Huan/0000-0002-9324-0200; Molnár, Tamás Gábor/0000-0002-9379-7121} } @article{MTMT:34034213, title = {Parameterized Barrier Functions to Guarantee Safety Under Uncertainty}, url = {https://m2.mtmt.hu/api/publication/34034213}, author = {Alan, Anil and Molnár, Tamás Gábor and Ames, Aaron D. and Orosz, Gábor}, doi = {10.1109/LCSYS.2023.3285188}, journal-iso = {IEEE CONTROL SYST LETT}, journal = {IEEE CONTROL SYSTEMS LETTERS}, volume = {7}, unique-id = {34034213}, year = {2023}, eissn = {2475-1456}, pages = {2077-2082}, orcid-numbers = {Alan, Anil/0000-0002-9778-8249; Molnár, Tamás Gábor/0000-0002-9379-7121; Ames, Aaron D./0000-0003-0848-3177; Orosz, Gábor/0000-0002-9000-3736} }
