Central to this objective is developing control and navigation stacks that avoid conservatism, presumed to be measured by a performance metric, while being provably and practically safe. A crucial element that must be accounted for is that controllers, which are typically designed for and tuned in laboratory or highly monitored industrial settings for a specific scenario, may experience a drop in performance and lose their safety guarantees when used elsewhere. It is of paramount importance therefore to import robots with the capability to adapt their controllers online to customize responses to a priori untested environments.\r\n\r\nIn this dissertation, I present (1) tools to adapt any parametric controller using a model-based approach to achieve simultaneous satisfaction of multiple state constraints and enhanced performance; (2) a numerical scheme for predicting future state distributions in systems governed by stochastic dynamics with state-dependent disturbances, which can be utilized in model-predictive approaches; and (3) a method to assist decision-making on dropping (disregarding) constraints when it is not feasible to satisfy all constraints simultaneously.\r\n\r\nA significant part of the dissertation also focuses on a specific safety-critical control method - control barrier functions (CBF). The CBF-based controllers have garnered interest in recent years due to their ease of implementation. However, finding a theoretically valid CBF remains a challenge and in practice, they are prone to performance degradation and safety violations, especially when multiple CBFs are imposed together. This dissertation introduces a new notion of CBFs, called Rate-Tunable CBFs, that allows for time-varying parameters in theory and online tuning in practice.", "occurrence_notes":"and on Zoom", "guid":"128827-21861667@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/128827", "building_id":"1005418", "building_name":"Ford Robotics Building", "campus_maps_id":"647", "room":"Atrium", "location_name":"Ford Robotics Building", "has_livestream":0, "cost":"", "tags":["Michigan Robotics","Robotics"], "website":"https:\/\/umich.zoom.us\/j\/99785238915", "sponsors":[ { "group_name":"Michigan Robotics", "group_id":"3998", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2024\/11\/event_128827_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2024\/11\/event_128827_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2024\/11\/event_128827_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2024\/11\/event_128827_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2024\/11\/event_128827_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2024\/11\/event_128827_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2024\/11\/event_128827_original-1.png" }, "occurrence_count":1, "first_occurrence":21861667 } , "128685-21861491": { "datetime_modified":"20241104T132955", "datetime_start":"20241114T150000", "datetime_end":"20241114T160000", "has_end_time":1, "date_start":"2024-11-14", "date_end":"2024-11-14", "time_start":"15:00:00", "time_end":"16:00:00", "time_zone":"America\/Detroit", "event_title":"Special Interdisciplinary QC-CM Seminar | Unveiling the Nexus Between Real and Momentum Space Skyrmion in Correlated Systems", "occurrence_title":"", "combined_title":"Special Interdisciplinary QC-CM Seminar | Unveiling the Nexus Between Real and Momentum Space Skyrmion in Correlated Systems: Shizeng Lin (Los Alamos National Laboratory)", "event_subtitle":"Shizeng Lin (Los Alamos National Laboratory)", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"In this talk, I will explore the emergent physics resulting from the complex interaction between real-space and momentum-space topology in strongly correlated quantum materials, with a particular focus on skyrmions. Using quantum Hall and quantum spin Hall insulators as key examples, I will explain the mechanisms behind skyrmion formation through electron doping in these correlated and gapped topological systems. We provide a detailed analysis of the phase diagrams and the formation of skyrmion lattices within the Kane-Mele-Hubbard model, supported by calculations from both the unrestricted real-space Hartree-Fock and density matrix renormalization group methods. In these systems, the doped electron and skyrmion form a composite object whose density is governed by the doped electron density. This electron-skyrmion bound state is stabilized by the coupling between the orbital magnetization of the Chern band and the emergent magnetic flux generated by the skyrmion. Moreover, we find that doping induces quantum anomalous Hall crystals, which exhibit quantized Hall conductance and broken translational symmetry. Our theory offers an intrinsic mechanism for the experimentally observed robust quantum anomalous Hall insulator over an extended doping range near a filling factor of \u03bd = 1 in twisted transition metal moir\u00e9 superlattices.\r\n\r\nReference: Miguel Gon\u00e7alves and Shi-Zeng Lin, arXiv:2407.12198\r\n\r\nShort-bio:\r\nShizeng Lin completed his Ph.D. at the National Institute for Materials Science and the University of Tsukuba in Japan.
