Conference Record of the IEEE Industry Applications Society Annual Meeting (IAS)

作者： D.R. Seidl T.L. Reineking R.D. Lorenz Department of Electrical & Computer Engineering Manufacturing Systems Engineering Program University of Wisconsin Madison Madison WI USA

A special neural network topology has been developed that compensates for friction in precision, position controlled mechanisms. A major contribution is that knowledge of the friction's form is used to determine the neural network's structure. This unique approach solves network sizing and weight initializing problems. The friction model is used for feedforward decoupling of friction-induced torque. The neural network also explicitly incorporates inertia compensation and linear feedback control. Another contribution is a demonstration of the trajectory dependence of static friction compensation with a discrete time controller. The authors include both the theoretical formulation and practical implementation results for the control of a commercial DC motor having a significant amount of static friction.< >

CORONA-POLED NONLINEAR POLYMERIC FILMS: IN SITU ELECTRIC FIELD MEASUREMENT, CHARACTERIZATION AND ULTRASHORT-PULSE APPLICATIONS

引用

Journal of Nonlinear Optical Physics & Materials 1992年第1期1卷 73-102页

作者： A. KNOESEN N.E. MOLAU D.R. YANKELEVICH M.A. MORTAZAVI A. DIENES Department of Electrical Engineering and Computer Science Organized Research Program on Polymeric Ultrathin Film Systems University of California Davis CA 95616 USA

Electric poling at field intensities approaching the dielectric strength of the film is possible with corona poling. Polymeric thin films with large second-order nonlinearities can be created with this poling technique. In this paper, the corona poling of nonlinear polymeric films at elevated temperatures, processing, characterization and possible ultrashort-pulse applications are reviewed. An experimental technique is presented to measure the electric field during poling of the nonlinear polymeric film. The characterization of orientational order in corona-poled nonlinear polymeric films and the effects associated with the large electric field during poling are discussed. Poled polymeric thin films are uniquely suited for second-order nonlinear optical applications of ultrashort pulses (< 50 fsec) since minimal pulse spreading occurs. The sum-frequency ultrashort-pulse application of nonlinear polymeric thin films and limitations of the thin polymeric films are discussed. Experimental results are presented of a side-chain nonlinear polymer that is ideally suited for ultrashort-pulse applications.

Integration has become a self-evident goal in today's manufacturing enterprises. Since the late 1970's, numerous major efforts have been launched worldwide to develop, employ, and deploy information technology for integration as a strategic weapon to compete in the global marketplace. This paper discusses a unique approach to the integration problem regarding metadata management, global query and concurrent systems administration. This approach has been shown to be effective in a prototype system, the Rensselaer Polytechnic Institute Metadatabase System. The metadatabase model incorporates both data and knowledge in order to accomplish information integration across manufacturing functions. The system's primary components and major functionalities are discussed and illustrated in detail through the use of an extended example of a pilot manufacturing system. © 1992 EEE.

INTEGRATION OF SHIP CONTROL-systems FOR TOTAL SHIP SURVIVABILITY

引用

NAVAL ENGINEERS JOURNAL 1992年第4期104卷 114-116页

作者： SIMPSON, HL FAMME, JB TAYLOR, B Joseph Famme:is the manager of marine systems CAE-Link Silver Spring Maryland. Mr. Famme joined Link in 1983 where he is responsible for developing marine products including digital control and monitoring systems for ships and submarines. Prior to joining Link then Commander Famme served in the U.S. Navy in all shipboard assignments including command of an FF-1052 class frigate. His engineering duties included supervising new construction sea trials and major mid-life ship overhauls. Mr. Famme has written concept papers defining architectures for future platform control systems and has worked within the simulation industry to introduce the use of distributed computer-based systems for training. He is currently working with various naval organizations and shipbuilding companies to develop the next generation of integrated digital control systems for ships and submarines. Barry Taylor:is the manager of marine systems at CAE Electronics Montreal Canada. CAE is currently supplying the integrated control systems for four classes of ships: the Canadian Patrol Frigate the DDH-280 the USN MHC-51 Minehunter and the SA'AR 5 corvette under construction at Litton - Ingalls Shipbuilding. Prior to joining CAE Electronics in 1987 then Commander Taylor served in the Canadian Navy as an engineering duty officer. His tours included sea duty as the engineering officer on five ships and shore duty assignments including one in the Directorate responsible for ship machinery control systems in the Canadian Navy. Commander Taylor was also the program manager for the Shipboard Integrated Machinery Control System Advanced Development Model (SHINMACS ADM). He has had numerous papers published on integrated ship control systems.

Effective damage control in naval ships has always been an important element of the naval combat equation. After receipt of battle damage, the ship's offensive operational capability depends upon its ability to support or restore vital systems. This in turn depends on the degree of initial damage, the damage control readiness condition of the ship, and effectiveness of the crew in applying the ship's damage control doctrine. In addition to conventional shell, mine, and torpedo threats, the speed and lethality of modern weapon systems presents an increased requirement for damage control readiness. New technology for the monitoring and control of the ship's hull, mechanical, electrical, and damage control (HME&DC) systems is now available with the potential for improving damage control readiness and for aiding the ship's commander in executing his damage control doctrine. This paper will describe the evolution of ship control systems, and discuss the application of current ship control systems technologies to damage control. It will recommend an optimum approach to meeting the requirements of damage control readiness posed by modern day threats, working within the U.S. Navy concept called Total Ship Survivability (TSS).

Otto Jons was one of the co-founders of Advanced Marine Enterprises Inc. in 1976 where he is corporate vice president engineering.

In the spring of 1990, the NavSea Chief Engineer initiated a project to improve the design, acquisition and construction (DAC) of U.S. Navy ships. The project's objectives are to reduce the time and cost of acquiring and operating Navy ships while improving their quality, unlike previous studies on the subject, the project utilizes a rigorous process analysis approach and attempts to use quantitative measures as the basis for recommending improvements. The paper is, of necessity, a status report on the progress of this project. Topics covered include: the DAC process;a look at the current state of ship acquisition time, cost, and quality;the methodology for process improvements;and early findings.

Quality and Reliability engineering International 1992年第5期8卷 391-412页

作者： Halverson, Mark Ozdes, Demir Mark Halverson:received a BSEE from the University of Michigan in 1972 followed by an MS in Computer Information and Control System Engineering in 1973 also from the University of Michigan. Mr. Halverson has worked predominantly on military and aerospace design projects for such companies as Litton and Northrop. He is a specialist in inertial navigation and control systems. He has also worked with PLG Inc. as a risk analyst on various projects including commercial military and space applications. Since 1986 Mr. Halverson is an aerospace consultant working in Europe where he among other activities codeveloped the BRAT probabilistic risk analysis program. Demir Ozdes:received his BSEE from Purdue University in 1958 and his MSEE from the University of Arizona in 1963. He has over 35 years of experience in electronic design system engineering optimal control system design and analysis as well as in the design analysis and simulation of synergistic navigation systems. He has worked at Northrop Teledyne SPC TRW and Litton. Since 1984 he has been a private consultant in the aerospace field in Europe and is co-holder of patents as well as being a co-developer of the BRAT probabilistic risk analysis program.

This paper takes a broad overview of the reliability and safety engineering practice as it is commonly exercised in the aerospace and military industries today, especially with respect to complex electronic equipment which typically includes considerable software content. A general deficiency is noted with regard to the system-level approach to reliability. It would appear that the system-level reliability activities are given less attention than is needed, while excessive emphasis is placed on component micro- physics, component failure models, and various component-oriented analyses. systems-level reliability topics, which predominate in the equipment reliability which is actually observed, are sometimes ignored by reliability engineers. Methods and practical philosophies to re-establish a solid system engineering foundation for contemporary reliability practice, which have been developed through the authors' experience in the field, are presented. Finally, an example analysis is shown to illustrate the concepts.

USS Ingraham (FFG-61) is the prototype ship for NavSea's Advanced Technical Information System (ATIS). ATIS is a digital technical library, which holds on optical disks the ship's 2,000 technical manuals and 73,000 drawing sheets. It contains a detailed ship's configuration index (derived from SCLSIS) to lead the user to the proper drawing or manual, and it replaces the ship's aperture cards and the second (library) copy of the technical manuals. ATIS, and the data standards established and tested through ATIS development, will be the technical library portion of micro-SNAP and SNAP III. It also forms an important part of NavSea's plans to utilize EDMICS data. This paper describes the goals and technical concepts behind the development of ATIS. Problems encountered, solutions developed, and lessons learned are detailed. Special attention was paid to the application of the computer Aided Acquisition and Logistic Support (CALS) standards, problems caused by conflicts and ambiguities in those standards, the standards. Original program goals are compared with actual operational experiences. Plans for future expansion are outlined, including applications of this technology in the availability planning and execution process. A comparison is developed among the various methods of optical imaging and their costs and benefits.

NAVAL ENGINEERS JOURNAL 1992年第2期104卷 69-80页

作者： BARON, NT CEBULSKI, DR Neil T. Baronis currently the team leader for the combat system topside design work for amphibious assault auxiliary mine warfare and Coast Guard ships. He sits on the IEEE SCC-28 Committee for personnel radiation hazards and is extensively involved in the EM engineering initiative at NavSea. Mr. Baron has lectured at the MIT Summer Professional Series on the subject of electromagnetic interference. While attending Marquette University he started his career with the Navy as a coop student supporting personnel radiation hazard assessments. After graduating with a BS in bio-medical engineering he took an electronics engineer position in the Systems Electromagnetic Division. Since then he has lectured on Navy training films and has developed several software packages which have pushed the state-of-the-art in EMI assessment. Mr. Baron has prepared several reports and professional papers. He has worked on several professional committees and in February of 1991 was awarded the “Young Engineer of the Year Award” which was presented by the D.C. Council of Engineering and Architectural Societies. Donald R. Cebulskiis currently the head of the Topside Design Division in the Naval Sea Systems Command Weapons and Combat System Directorate. He graduated from the University of Michigan with a bachelor's degree in 1963 and a master's degree in 1977 both in naval architecture and marine engineering. He started his career in 1964 at the Bureau of Ships and joined the Aircraft Carrier Section of the Arrangements Branch in Hull Design. During the past 25 years he has included almost every naval ship type in his ship arrangement experience and in October of 1988 he transferred to the Topside Design and Integration Branch in the System Electromagnetics Division Sea 06. Mr. Cebulski has written several papers on ship arrangements computer aided design and ship topside design. He prepared and presented lectures at the MIT Professional Series on ship topside design and has served on many ASNE committees. He is currently the

Electromagnetic interference (EMI) is one of the major contributors to mission degradation in our fleet today due to the increase in population and sensitivity of both topside and below deck electronic systems. Sensitive combat systems designed to counter intelligent and deceptive targets can be confused by the complex intra-ship EM environment. This can cause identification failure or losing "track" of a hostile or incoming missile or even engaging "friendly targets." Topside design and integration efforts have been used to reduce EMI, but this is not the total solution to the problem. A program of total ship and system EMI assessment and control must be implemented. This program must exploit electromagnetic compatibility (EMC) optimization in electronic circuit design and take advantage of and (in some cases) direct topside shapes and structures to control the propagation of desired and undesired EM energy. Positive and active control of EM design characteristics are absolutely required before optimum combat system effectiveness can be realized. This paper will describe the current topside design process, EMC improvements being made, and how the process is being integrated into, and is dependent upon, the ship design process. It will give examples of some of the major mission degrading EMI problems in the fleet today and how past problems were solved with existing EM analysis programs. It will also discuss the control of EM energy in new design through the use of techniques being developed such as ray tracing and ray casting. The paper projects where the challenges lie for future topside and EM engineering designers and describes how the equipment technology transfer process must be better integrated to meet the challenge of effective EMI control.

IEEE International Conference on Robotics and Automation (ICRA)

作者： J.S. Joshi A.A. Desrochers CIM Program Digital Equipment Corporation Troy NY USA Electrical Computer and Systems Engineering Department Rensselaer Polytechnic Institute Troy NY USA

A Petri-net-based integrated model for the performance analysis of network and database transactions, generated by manufacturing clients for the computer resources, which are acting as the servers, is discussed. A Petri-net-based multifaceted integrated modeling (PNBMIM) approach to investigate the relevant system integration issues between the logical and the physical access of the information in the manufacturing system is described. The PNBMIM approach proposes an integrated conceptual framework for modeling and performance (both structural and behavioral) analysis of data flow and communication flow. This framework should provide some answers to the impact of relative time-scales on the coupling and decoupling of the various levels of a computer integrated manufacturing (CIM) system and identify the time-scales where integration becomes important.< >
