A Multilevel Newton Algorithm with Macromodeling and Latency for the Analysis of Large-Scale Nonlinear Circuits in the Time Domain

引用

IEEE Transactions on Circuits and systems 1979年第9期26卷 733-741页

作者： Rabbat, Guy N.B. Hsieh, Hsueh Y. Sangiovanni-Vincentelli, Alberto L. Advanced Analysis Group IBM Data Systems Division Laboratory Hopewell Junction Ny 12533 United States Department of Electrical Engineering and Computer Sciences University of California Berkeley CA 94720 United States

Analysis techniques which take advantage of the structural properties of large-scale electrical networks are discussed. Exact macromodels of a subnetwork are defined and a sufficient condition on the subnetwork equations for the existence of a macromodel is given. A multilevel Newton algorithm based on macromodels is presented. The algorithm Is shown to have local quadratic convergence provided that suitable conditions on the continuity and nonsingularity of the Jacobian of the network equations are satisfied. The concept of latency for the analysis of large scale networks in the time domain is discussed. The relationship between latency and numerical integration methods is investigated. © 1979 IEEE

THE SHINPADS SERIAL DATA BUS

引用

Naval Engineers Journal 1979年第2期91卷 164-172页

作者： KUHNS, RICHARD C. The Author received his BS degree in Electrical Engineering from the South Dakota State University in June 1960. He joined SPERRY UNIVAC Defense Systems Division in June 1960 where he is now Manager of the Surface Combat Systems Group in the Navy Systems Engineering Department. He is currently active in the development of Navy Command and Control Systems. He has been active in the field of Navy systems computer digital communications analysis and design and was responsible for the system design of the NTDS Serial Interface specified in Military Standard MIL-STD-1397.

The Shipboard Integrated Processing And Display System (SHINPADS) Serial Data Bus is a high speed digital interconnect system designed to provide a real time data bus communication facility for Naval Electronic systems. The Serial Data Bus (SDB) can be used to interconnect devices currently using Military Standard MIL‐STD‐1397 Input/Output Interfaces and it has been designed to suit the needs of Naval Combat systems. The SHINPADS Serial Data Bus was specified with an eye to the future. A large growth margin was designed into the system, while minimizing costs, by properly distributing functions between software, firmware, and hardware. The Serial Data Bus protocol enables future evolution to Fiber Optic Transmission without impacting system software. The Serial Data Bus provides the potential for accomplishing many of the features attributed to Distributed Processing systems. However, the accomplishment of Distributed Processing improvements can only occur through proper and enlightened system design. © 1979 American Society of Naval Engineers

THE AN/UYK‐502(V) MICROcomputer

引用

Naval Engineers Journal 1979年第2期91卷 173-178页

作者： WILLIAMS, PAUL F. ANDERSON, JOHN M. Mr. Paul F. Williams:received his BS degree in Electrical Engineering from the University of Minnesota in December 1965. He joined SPERRY UNIVAC Defense Systems Division in January 1966 where he is now the Manager of the Computer Product Planning Group in the Marketing Department. He has been active in the development of new computer system architectures and new computer development including the AN/UYK-20 and AN/UYK-23. In addition he has worked with a number of Navies in the development of shipboard and landbased systems and has participated in the development of NATO Shipboard Standard Interfaces. Mr. John M. Anderson:received his BS degree in Electrical Engineering from the University of Washington in June 1969. He joined SPERRY UNIVAC in July 1970 where he is now a Senior Design Engineer in the Product Development Group. He is currently active in the development of the AN/UYK-520 Microcomputer and additionally has been active in the fields of digital logic design programming and computer testing.

The AN/UYK‐502 Microcomputer is a full‐scale, general‐purpose 16‐bit militarized computer designed to emmulate the AN/UYK‐20 and AN/AYK‐14, and to be implemented in a shipboard system employing distributed system architecture. Ship System Data Busses require microcomputers to be located near or within ship subsystems, with system interconnection being made through a common data bus. To implement this type of system architecture, a low cost, modular microcomputer capable of handling the bus “handshake” through a standard interface is required. The AN/UYK‐502(V) uses software common to minicomputers which allows different computer configurations to be implemented with bus architecture. The resulting system can then be maintained with a single set of support software programs thus significantly lowering system life cycle costs. The computer is offered in three physical packages: the Card Kit, Chassis Assembly, and Cabinet Assembly. Flexible options of the AN/UYK‐502(V) allow the user to tailor the system to the application needs. These options include the Central Processing Expansion Unit;main memory up to 2S6K (where K = 1024);memory parity;choice of 1 to 64 input/output (I/O) channels;parallel and/or serial I/O;and power supply selection. © 1979 American Society of Naval Engineers

PROCESSOR-PROCESSOR DIALOGUE THROUGH EXISTING INPUT-OUTPUT CHANNELS.

引用

IEE J Comput Digital Tech 1978年第4期1卷 125-130页

作者： Witten, Ian H. Jenkins, Richard L. Department of Computer Science University of Calgary Calgary Canada Man-Machine Systems Group Department of Electrical Engineering Science University of Essex Colchester UK

The multitude of computer input-output devices currently marketed, and their decreasing cost, often raises problems of transfer of information between different media. These are aggravated by the ready availability of low-cost processing power in the form of mini- and micro-computers, which encourage the development of many separate computer configurations, each with their own input-output facilities. Processor-processor links using existing input-output channels constitute a cheap and simple way of overcoming these incompatibilities. This paper discusses the software and hardware technology for handling such links, placing emphasis on simple, easily-implementable protocols and hardware rather than on maximum bandwidth utilization and automatic error correction.

Generalization of adaptive observer and method of optimizing its convergence properties

引用

Journal of Dynamic systems, Measurement and Control, Transactions of the ASME 1977年第1期99卷 15-22页

作者： Kim, C.H. Lindorff, D.P. Autonetics Group Marine Systems Division Rockwell International Anaheim CA United States Department of Electrical Engineering and Computer Science University of Connecticut Storrs CT United States

This paper concerns a generalization of the design of the adaptive observer, and an investigation of its convergence properties. By application of hyperstability theory the design freedom is enlarged to permit use of time variable adaptive gains. Based on the assumption of periodic excitation, and with the aid of Floquel Theory a new convergence criterion is defined. By this means the effects of adaptive gains and input frequencies upon convergence lime are evaluated. Structural properties of the adaptive observer are compared with other adaptive schemes, in particular with regard to bias due to noise. © 1977 by ASME.

The real-time command and control environments characteristic of tactical military systems and industrial process control systems place unique and conflicting design requirements on a support computer system. These requirements include fast context switching, selective protection of programs and their files, controlled sharing of program and files, high processing speed, flexible, yet fast priority structure for interrupts and program execution, flexible high-speed I/O and flexible intercommunication and control for interacting programs. This paper describes a new computer system now being prototyped to satisfy these requirements. The system design includes a number of unique features relating to the efficient implementation of a flexible virtual memory addressing system for the stringent real-time environment. © 2018 ACM, Inc.
