But guarantees on upper bounds of end-to-end communication delays are required for certification purposes. The objective of this paper is to present an improved modeling approach using timed automata for calculation of exact worst case delays. This approach takes advantage of local scheduling of flows. Moreover, it can cope with larger network configurations than existing approaches based on timed automata, thanks to a port by port analysis which reduces the search space.","PeriodicalId":201440,"journal":{"name":"2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114009486","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}

In systems subject to actuator saturation, a controller with this characteristics is highly prone to windup effect. Since linear design does not consider the actuator saturation this non linear behaviour may compromise the performance and even the stability of the system. One way to deal with this problem is to avoid saturation by selecting an actuator with larger capacity but it increases the implementation cost. In other cases, an anti-windup scheme is necessary. The main goal of the anti-windup strategy is threefold: to obtain a faster recovery of the system after saturation, to achieve less performance degradation and to preserve stability. In this paper three different anti-windup schemes have been selected from the available literature to address the windup problem in digital repetitive control. The design and implementation issues are discussed. A simulation example compares the results when saturation is reached either during the transient response or in steady state.","PeriodicalId":201440,"journal":{"name":"2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114213733","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}

In concrete it manages three well accepted standards: CAEX for topology, COLLADA for kinematics and geometry, and PLCopen for logic data. This paper is focused in the logic data.

The approach defines three Domain Specific Models: control specification and hardware and software architectures. The software model uses the PLCopen XML interface for expressing IEC 61131–3 automation projects. The information contained in the whole application model is processed to generate the temporal model of the application.

PLCs are today mostly programmed in the languages of the IEC 61131 standard which are not ready to meet the new challenges of widely distributed automation systems. Currently, different solutions are available from industry and research: an extension of IEC 61131 which includes object oriented programming, the adoption of the new standard IEC 61499 or the implementation of supervisory control. All these solutions present different problems which are briefly recalled in the paper.

A precise estimation of such a task parameter is quite difficult to achieve, because execution times depend on many factors, including the task structure, the system architecture details, operating system features and so on. While some of these features are not under our control, selecting a proper scheduling algorithm can reduce the runtime overhead and make the WCETs smaller and more predictable. In particular, since task execution times can be significantly affected by preemptions, a number of scheduling methods have been proposed in the real-time literature to limit preemption during task execution. In this paper, we provide a comprehensive overview of the possible scheduling approaches that can be used to contain preemptions and present a comparative study aimed at evaluating their impact on task execution times.","PeriodicalId":201440,"journal":{"name":"2010 IEEE 15th Conference on Emerging Technologies & Factory Automation (ETFA 2010)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123955721","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}
