In this paper, we consider the model class of hybrid automata whose dynamics are defined by affine differential equations. Given a set of time-series data, we present an algorithmic approach to synthesize a hybrid automaton exhibiting behavior that is close to the data, up to a specified precision, and changes in synchrony with the data. A fundamental problem in our synthesis algorithm is to check membership of a time series in a hybrid automaton. Our solution integrates reachability and optimization techniques for affine dynamical systems to obtain both a sufficient and a necessary condition for membership, combined in a refinement framework. The algorithm processes one time series at a time and hence can be interrupted, provide an intermediate result, and be resumed. We report experimental results demonstrating the applicability of our synthesis approach."}],"publication_status":"published","date_published":"2021-05-01T00:00:00Z","month":"05","article_processing_charge":"No","tmp":{"image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode"},"date_updated":"2023-08-07T13:49:33Z","file":[{"checksum":"4c1202c1abf71384c3ee6fea88c2f80e","relation":"main_file","access_level":"open_access","creator":"kschuh","file_name":"2021_HSCC_Soto.pdf","content_type":"application/pdf","date_updated":"2021-05-25T13:53:22Z","date_created":"2021-05-25T13:53:22Z","file_size":1474786,"success":1,"file_id":"9424"}],"type":"conference","day":"01","ddc":["000"],"project":[{"name":"The Wittgenstein Prize","_id":"25F42A32-B435-11E9-9278-68D0E5697425","grant_number":"Z211","call_identifier":"FWF"},{"grant_number":"754411","name":"ISTplus - Postdoctoral Fellowships","_id":"260C2330-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"}],"keyword":["hybrid automaton","membership","system identification"],"isi":1,"acknowledgement":"This research was supported in part by the Austrian Science Fund (FWF) under grant Z211-N23 (Wittgenstein Award) and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie grant agreement No. 754411.","file_date_updated":"2021-05-25T13:53:22Z","year":"2021","language":[{"iso":"eng"}],"_id":"9200","ec_funded":1,"conference":{"end_date":"2021-05-21","location":"Nashville, TN, United States","start_date":"2021-05-19","name":"HSCC: International Conference on Hybrid Systems Computation and Control"},"citation":{"ieee":"M.
