Instead of exhaustively enumerating all marking vectors consistent with any given event occurrence, we do a representation-based state estimation, where we compute a compact representation structure that characterizes these markings. Our representation structure is based on a representative Petri net (RPN), whose single initial marking represents all markings of the system λf-LPN consistent with the sequence. These representations can be directly used to solve other DES-related problems, such as fault diagnosis. Our approach can compute representations of any λf-LPNs. In addition, for a class of unbounded λf-LPNs, our approach can compute representations that do not grow indefinitely as more events occur.</p></div>","PeriodicalId":37894,"journal":{"name":"IFAC-PapersOnLine","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2405896324000910/pdf?md5=290534b56359f6de8d1b1137c2aafc5b&pid=1-s2.0-S2405896324000910-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141636748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
