At the base of the system stays the WiSensors, a low power 802.11 Wi-Fi device powered by an RN-131C chip to which various sensors and actuators can be connected. Depending on the application requirements, a network of WiSensors with different sensing and action capabilities can be created. For each application a coordinator responsible for managing devices in the network and communicating with the application server, is required. The proposed solution presents a high level of flexibility, implementing a dynamic reconfiguration mechanism where the coordinator can be reprogrammed to act according the specific application and user needs.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115609481","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}

When a fully-actuated robot is used, the robot reference trajectory is simply constructed by linking through line segments the middle points of common facets of successive traversed cells. This paper improves this approach by proposing three different optimizations that yield the waypoints through which the robot piecewise linear route is passing. The optimizations use different metrics defined as sums of norms for the linear segments that compose the route. The norms L1, L2 squared and L∞ are used and standard optimization problems result in each case. Examples are included for showing the usefulness of these optimizations, since shorter routes can be obtained under a negligible computational overhead.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125319363","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 evaluation has been performed by using Principal Component Analysis (PCA), as this non-supervised artificial intelligence technique reveals the structure of the original data and allows the evaluation of the clustering quality. It also allows an objective variable selection, as it indicates the most important variables which are contributing to the clustering of the data and which variables are redundant and thus may be discarded. The system has been tested for green peas (Pisum sativum), which is one of the most popular vegetable on the European horticultural market. The results show that the proposed PCA system can also be used as a stand-alone tool for traceability assessments, as it allows the assignment of the modeled country of origin by performing a binary (asymmetric) classification. The system is very user-friendly, even for non-specialists such as law enforcement officers, as its graphical interface is easy to understand.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123431804","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}

This paper proposes a new architecture for safety relevant systems that are using electric motors. Using this architecture one can diminish the range where the unsafe state is defined as off and understood as deactivated or as no assistance provided. Moreover, a case study for a four phase permanent magnet synchronous motor is conducted and the ability to overcome inserted failures using the new architecture in conjunction with a properly adapted control strategy is proven via Matlab/Simulink simulations.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123181859","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}

We consider both rotating consensus and consensus tracking algorithms and present convergence conditions. In the case of rotating consensus, sufficient conditions are derived under which all agents rotate around a common point. In the case of rotating consensus tracking, we show that all the agents can rotating around a dynamic virtual leader, when this leader is a neighbor of only a subset of a group of followers and all followers have only local interaction. Tools like matrix theory, linear system theory, and other mathematical skills are used for convergence analysis.

In real industrial processes, usually there are present nonlinearities, the time changing parameters of the equipment, noise and uncertainties. These processes are sometimes modeled by NARMAX models. The current paper approaches system modeling with NARMAX polynomials of a distillation process with the aid of the genetic algorithms technique. The high flexibility of NARMAX models is combined with the properties of genetic algorithms to search for solutions in highly dimensional and multimodal spaces in order to obtain a good prediction of the process output for a limited time interval and also to minimize process response time.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114830650","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 implementation cost is calculated emphasizing the most economical solutions. Low cost means less power consumed - green architectures, the CPU FPU logic core is much faster and the responses timing are short. The modern design tools handle digital systems with many outputs and represent them by cubes, for efficiency reasons. Talking as optimal, the implementation of the digital automaton can be reduced to a combinatorial one: synthesis using logic gates primitives and using floor planning design. The digital logic network that generates the control signals of the Finite State Machine (FSM) can be synthesized using the transfer matrix.","PeriodicalId":257135,"journal":{"name":"2015 19th International Conference on System Theory, Control and Computing (ICSTCC)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121724049","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}
