More specifically, we first apply linear regression to predict the (output) equipment health condition from the (input) operational parameters. This choice of linear model also allows us to propose an algorithm to reduce the number of operational parameters to be monitored for PdM purposes using t-statistics. Then, we follow a cross-validation based procedure to generate prediction error samples and apply a kernel method to construct the corresponding probability density function of the prediction error. Finally, the PdM decision can be made based on the likelihood of the predicted health condition exceeding a certain maintenance threshold. Our analysis using real data from a semiconductor etching chamber shows that the proposed PdM decision with the reduced dimension linear regression performs comparably to the one using full-scale linear model and can be used for better maintenance planning compared to the existing practice of fixed-schedule maintenance.","PeriodicalId":20477,"journal":{"name":"Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA)","volume":"4 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75145784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently the Flexible Time-Triggered Replicated Star for Ethernet (FTTRS) has been proposed as a communication subsystem that satisfies these two attributes. It is based on the master/multi-slave Flexible-Time Triggered (FTT) communication paradigm and relies on two custom switches, each with its own embedded FTT master. Both masters are active simultaneously and provide the same service. Specifically, they simultaneously and periodically broadcast so-called trigger messages (TMs) in a redundant manner to make them robust to transient channel faults. One of the functions of these TMs is to divide the communication time into rounds called elementary cycles (ECs). For the correct operation of FTTRS, it is important that all slaves agree when each EC starts and ends. A mechanism to achieve this has been recently proposed. This paper presents a first implementation of this mechanism and a series of experimental tests that constitute a first step towards building a prototype of an FTTRS network.","PeriodicalId":20477,"journal":{"name":"Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA)","volume":"16 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78761149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, developing such systems presents difficulties in ensuring time and timing accuracy due to unpredictable computation time, ambiguities in program concurrency, and behavioural inconsistency between model and implementation. However, in contrast, the models in our approach are fully time-predictable by means of a logical time interval called a tick, while concurrency is automatically handled by the design semantics in a timing guaranteed manner. Meanwhile, the model-driven aspect of automatic code generation guarantees the behavioural consistency between model and implementation. We achieve our approach by using IEC 61499 function blocks and synchronous execution for syntax and semantics respectively. In this paper, we design a time-triggered protocol and a distributed motor synchronization as the network and application layers respectively. Then, we model the overall system for validation by performing composition of such layers. Furthermore, we explain how the logical time tick can be realized during the implementation in a way that the real-time requirement can be satisfied. Finally, the simulation and implementation results demonstrate the effectiveness of our approach.","PeriodicalId":20477,"journal":{"name":"Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA)","volume":"110 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79262813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
