This paper first presents a feed drive controller design that considers coupling effects among multi-axis. Although most feed drive controller design ignores coupling effects among multiple axes, inertia force caused by movement at one axis affects contact force between mechanical components at other axes and considering these coupling effects in controller design could improve control performance. Because coupling effects are generally unknown, we propose adaptive controller design and demonstrate its effectiveness by experiment. In addition, we discuss the extension of the proposed controller considering coupling effects to coordinate transformation based contouring control of feed drive systems.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128046274","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 this context, the applicability of Model Driven Development (MDD) and Model-Based Testing (MBT) methodologies for RTES have been gaining attention in the recent decade. MBT approaches, in general, helps in automatically generating test cases using models extracted from software artifacts. However, currently none of the existing MBT approaches deal with generating test artifacts for executing and verifying these test cases in memory size constrained and code-size critical RTES. To address this, an integrated MBT approach for executing the test stimuli in the RTES (without dynamic source code instrumentation) is discussed in this paper. A prototype implementation is discussed followed by an experimental evaluation of this approach for an RTES example. Finally, this paper presents a perspective on the applicability of model-based approach for industrial RTES projects.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130256026","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}

Several modeling formalisms are widely used within this area. The work presented in this paper aims to contribute for the usage of Petri nets as the system-level specification language within model-based development of embedded systems using co-design techniques. System model partitioning into modules and components ready to be implemented in hardware or software and be deployed into a distributed platform is a major concern within co-design methodologies. Having Petri net as underlying modeling formalisms the net splitting operation can be used in order to decompose the model into several sub-models. The resulted sub-models can be seen as components and executed in parallel communicating using directed synchronous communication channels. In this paper it is presented how to modify the splitted model in order to be considered as composable modules, supporting module reutilization, which is a key impact factor within engineering activities. The proposed techniques rely on keeping the module interface unchanged in order to support the integration of the module in new situations.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131670819","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}

To address these problems, the Embedded Reconfigurable Architectures project (ERA), investigates innovations in both hardware and tools to create next-generation embedded systems. Leveraging adaptive hardware enables maximum performance for given power budgets. We design our platform via a structured approach that allows integration of reconfigurable computing elements, network fabrics, and memory hierarchy components. Commercially available, off-the-shelf processors are combined with other proprietary and application-specific, dedicated cores. These computing and network elements can adapt their composition, organization, and even instruction-set architectures in an effort to provide the best possible trade-offs in performance and power for the given application(s). Likewise, network elements and topologies and memory hierarchy organization can be selected both statically at design time and dynamically at run-time. Hardware details are exposed to the operating system, run-time system, compiler, and applications. This combination supports fast platform prototyping of high-efficient embedded system designs. Our design philosophy supports the freedom to flexibly tune all these hardware elements, enabling a better choice of power/performance trade-offs than that afforded by the current state of the art.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129650506","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}

The energy consumption of the nodes can be effectively managed by a decrease in the response packets of the neighbors under the joining requests of the mobile nodes. However, static hysteresis causes a decrease in the joining period for preventing the ping-pong phenomenon. In order to optimize the association rate, dynamic hysteresis is used for the proposed method. To evaluate the performance of the proposed scheme, the association rate is investigated and analyzed through computer simulations. Simulation results show that the proposed method enables efficient joining according to the mobility of nodes in IWSNs.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132603479","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}

The risk analysis is then used to calculate the risk of a specific situation affecting an industrial plant. The situation, characterized by the symptoms, has a risk value which is estimated from the information stored on the system concerning the probability of occurrence of a new problem when a specific action is implemented. For the sake of system robustness it is expected that this knowledge grows along the life-cycle of an industrial plant. Depending on the knowledge available and on the risk of the situation, the adequate procedure is suggested for promptly reaction and problem elimination.","PeriodicalId":378407,"journal":{"name":"2011 9th IEEE International Conference on Industrial Informatics","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122368096","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}
