Differential flatness will be utilized for planning the generator's trajectory as there is a one-to-one correspondence between output curves and trajectories for states and inputs. Flat outputs of the generator are taken to be the generator's complex current injected into the power network, and inputs are taken to be the power set-point for the governor and reference voltage for the voltage regulator. The utility of the property and it's application is demonstrated through trajectory planning, open-loop control and simulation of a single machine infinite bus system, as well as a simple linearizing feedback scheme to a 9-bus system with constant impedance loads.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"147 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125864380","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 paper we will take an explorative view on Electric Mobility and match developments in that area with Systems of Systems Engineering. We will also present a case study on charging many Electric Vehicles, where we will match business opportunities and technical feasibility to the transition from early adopters to the early majority as main Electric Vehicle users.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131649403","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}

DES has been used for many applications ranging from aeronautics to health care to transportation. In this paper, we apply a novel DES architecture that is dynamically adaptable to support decision making for multiple and diverse mission areas (i.e., missile defense, cyber offense, remote object recognition and location). This paper also advances traditional probabilistic solutions for these mission areas by extending analytics into the time domain through integration of Bayesian statistics into DES. Using DES in this way provides a straight forward way to determine the overall probabilities for a complex set of time-based events. DES also allows for random sampling of the input probability distributions and, through iterative computation, provides Monte Carlo analysis with which to derive confidence intervals for the overall probability for the simulated conditions. Confidence interval accuracy is of great importance to the simulation end-user with respect to course of action decisions.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"2673 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134544907","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}

Our ongoing work proposes virtual reality operator training for the micro-robotic cell injection procedure. The interface between the operator and the system can be achieved in many different ways. The computer keyboard is ubiquitous in its use for everyday computing applications and also commonly utilized in virtual reality systems. Based on the premise that most people have experience in using a computer keyboard, as opposed to more sophisticated input devices, this paper considers the feasibility of using a keyboard to control the micro-robot for cell injection. In this study, thirteen participants underwent the experimental evaluation. The participants were asked to perform three simulated trial sessions in a virtual micro-robotic cell injection environment. Each session consisted of ten cell injection trials and relevant data for each trial were recorded and analyzed. Results showed participants' performance improvement after the three sessions. It was also observed that participants intuitively controlled multiple axes of the micro-robot simultaneously despite the absence of instruction on how to do so. This continued throughout the experiments and suggests skills transfer from other keyboard based interactions. Based on the results provided, it is suggested that keyboard control is a feasible, simple and low-cost control method for the virtual micro-robot.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114523304","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 proposed approach, which is constructed based on batch clustering and real-time clustering techniques, incorporates historical and real-time data to predict the time and location of severe braking events. Batch clustering is implemented with the combination of subtractive clustering and fuzzy c-means clustering to generate clusters representing the initial correlation patterns. Real-time clustering is then developed to create and update real-time correlation patterns on the foundation of the batch clustering using evolving Gustafson Kessel Like (eGKL) algorithm. Real-time driving data of operating vehicles each equipped with a data acquisition and wireless communication platform are used to validate the proposed strategy. Drivers can be notified of the potential severe braking locations through maps, and recognize the events occurrence at different times and locations through the variation of the identified correlation patterns.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129055650","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}

Often, the SoS is modeled in all its complexity, at a single level of abstraction or level of detail. Instead of a “mega-model” approach, a standards-based, layered “model of models” (MOM) approach is what is necessary. This paper discusses use of the Object Management Group (OMG) Unified Profile for DoDAF and MODAF (UPDM) for architecture modeling. UPDM supports a MOM approach by enabling the development of integrated model layers such as an outcomes model layer and a component layer. An integrated, layered MOM is in keeping with the Model-Based Systems Engineering (MBSE) approach. The model layers can be referenced when detailed analysis is required, or hidden when a SoS viewpoint is required.","PeriodicalId":399744,"journal":{"name":"2015 10th System of Systems Engineering Conference (SoSE)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121040965","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}

Moreover, a comparison of the computational complexity of the controller between the proposed control scheme and the one considering Euler angles is carried out.
