In this paper, we extend the observer/control strategies previously published in [25] to an n -link, serially connected, direct drive, rigid link, revolute robot operating in the presence of nonlinear friction effects modeled by the Lu-Gre model. In addition, we also present a new adaptive control technique for compensating for the nonlinear parameterizable Stribeck effects. Specifically, an adaptive observer/controller scheme is developed which contains a feedforward approximation of the Stribeck effects. This feedforward approximation is used in a composite controller/observer strategy which forces the average square integral of the position tracking error to an arbitrarily small value. Experimental results are included to illustrate the performance of the proposed controllers.

113th Annual ASEE Conference and Exposition, 2006

作者： Carpinelli, John Calluori, Raymond Briller, Vladimir Deess, Eugene Joshi, Kamal New Jersey Institute of Technology United States Department of Electrical and Computer Engineering NJIT's Master Teacher Committee Office of Institutional Research New Jersey Institute of Technology United States National Science Foundation Funded Research Project Studying Jury Service and Civic Behavior Outcomes Assessment NJIT United States Institutional Research and Planning New Jersey Institute of Technology United States University of Washington University of Colorado on an NSF Funded Nationwide Study of Civic Engagement United States

During the past few years, the New Jersey institute of technology (NJIT) has initiated several projects to determine best practices in distance learning education and to apply them to courses in the Newark College of Engineering. The engineering college has lagged behind other colleges within the university in developing and implementing distance learning courses, and concerns about the quality of distance learning courses are one of the main reasons for this. The Office of Institutional Research and Planning at NJIT has undertaken a study of distance learning courses offered during the 2003-2004 academic year. The study examines a total of 150 courses, 3, 491 students and 7,701 course enrollments;approximately 1/5 of the enrollments are in distance learning courses and the remaining students enrolled in traditional face-to-face courses and served as a control group. The study examines a wide variety of parameters, including overall course performance, student satisfaction with the course and the instructor, delivery format for distance learning courses (multimedia, text, multimedia + text), instructor rank, instructor training for distance learning instruction, distance learning platform (WebCT® and WebBoard®), and ease of use of technology. This paper presents the results of this study and how they can be applied to produce improved distance learning courses in the engineering college, in all colleges within NJIT, and at other universities. Among its most significant results, the study highlights the need for instructors to receive training in teaching, learning, and technology;the preference of students for courses that use multiple delivery formats;and the greater student satisfaction at NJIT for courses that use WebCT as their asynchronous learning network platform. © American Society for Engineering Education, 2006.

Hybrid simulation includes both functional computer software models and actual hardware subsystems operating as an integrated whole. A ''hot test bed'' or a ''hybrid simulator-emulator'' enables design engineers to evaluate conceptual models in a more realistic real-lime context, but places increased cognitive demands on the designer. This paper describes an architecture, and results from a prototype implementation, for a design decision support system to allow a designer to make more productive and cost effective use of a test bed system.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELS for the Concurrent Engineering of Layered Structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCS), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FSQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

Panels and all other structural components of surface ships and submarines vibrate when the vessel is underway. The vibratory motions are primarily excited by the power plant. At operational (design) speeds, panels vibrate in their fundamental modes and those associated with their higher harmonic frequencies. The panel motions have rather well-defined energy spectra, which depend on both the structural design, position of the panel and the rotational speed of the single or multiple power plants. The panel motions will interact with the vortices in the adjacent turbulent boundary layer. The interaction can result in either an increase in the frictional drag or a decrease. Because of this, the argument is made that the designs of the panels and their support systems should include considerations of this hydroelastic effect.

The objectives of Human Engineering (HE) are generally viewed as increasing human performance, reducing human error, enhancing personnel and equipment safety, and reducing training and related personnel costs. There are other benefits that are thoroughly consistent with the direction of the Navy of the future, chief among these is reduction of required numbers of personnel to operate and maintain Navy ships. The Naval Research Advisory Committee (NRAC) report on Man-Machine technology in the Navy estimated that one of the benefits from increased application of man-machine technology to Navy ship design is personnel reduction as well as improving system availability, effectiveness, and safety The objective of this paper is to discuss aspects of the human engineering design of ships and systems that affect manning requirements, and impact human-performance and safety The paper will also discuss how the application of human engineering leads to improved performance, and crew safety, and reduced workload, all of which influence manning levels. Finally, the paper presents a discussion of tools and case studies of good human engineering design practices which reduce manning.
