This paper examines a class of permanent magnet machines that offer advantages for clean power, UPS and IFS energy storage module applications. The chief feature of this class of machines is the ability to control the location and number of poles on the rotating field structure. Using this technology, motor-generators with integral flywheel high inertia can supply a constant frequency (for AC application) and constant voltage (AC or DC) output over a wide range of shaft rotation speed. This technology is proven and in service in many applications throughout the country, including severe environment service for weather radars. 400 kW and larger machines are under development which merit consideration for Navy requirements for clean power, uninterruptible power supply (UPS) and integrated power system (IFS) energy storage module applications and which could reduce or eliminate the need for battery backup systems. This capability can be backfit into current AC distribution systems and forward fit into IFS AC/DC distribution systems.

The V/STOL capability of the AV-8B Harrier is provided through a sophisticated combination of vectored thrust and aerodynamic technology. The proper interaction of the nozzle thrust and flap system is of extreme importance. Specific combinations of nozzle angle and flap position are employed to optimize both jet lift and aerodynamic lift. However, if the proper flap-nozzle position schedule is violated, the resulting thrust and flap impingement may cause a severe nose-down pitching moment sufficient to override the pilot control. Depending upon ground proximity, this condition creates a hazard which causes great potential for loss of aircraft and/or pilot. Flap impingement hazard was identified on the AV-8B aircraft as a potential catastrophic flight hazard. In response, a requirement was established to 1) study the severity of the flap impingement hazard on the AV-8B, 2) devise flight operational procedures which would minimize pilot exposure to the hazard potential and the resulting pilot control problems during flight, and 3) devise a training capability to familiarize pilots with flap impingement hazard characteristics and recovery procedures. This paper comprises the results of a study which utilized piloted flight simulation and fleet simulation trainers to meet these requirements.

作者： Lindley, Craig A. Computer scientist with the Knowledge-Based Systems Program the CSIRO Division of Information Technology North Ryde NSW 2113 Bldg. E6B Macquire University Campus Australia

This paper describes a behavioural competency level concerned with emergent scheduling of spacecraft payload operations. The level is part of a multilevel subsumption architecture model for autonomous spacecraft, and functions as an action selection system for processing spacecraft commands that can be considered "plans-as-communication." Several versions of the selection mechanism are described and their robustness is qualitatively compared. © 1994.

A valuable technique during concept development is rapid prototyping of software for key design components. This approach is particularly useful when the optimum design approach is not readily apparent or several known alternatives need to be rapidly evaluated. A problem inherent in rapid prototyping is the lack of a "target system" with which to interface. Some alternatives are to develop test driver libraries, integrate the prototype with an existing working simulator, or build one for the specific problem. This paper presents a unique approach to concept development using rapid prototyping for concept development and scenario-based simulation for concept verification. The rapid prototyping environment, derived from artificial intelligence technology, is based on a blackboard architecture. The rapid prototype simulation capability is provided through an object-oriented modeling environment. It is shown how both simulation and blackboard technologies are used collectively to rapidly gain insight into a tenacious problem. A specific example will be discussed where this approach was used to evolve the logic of a mission controller for an autonomous underwater vehicle.

AN AUTOMATA-THEORETIC FRAMEWORK FOR INTELLIGENT systems

引用

ROBOTICS AND COMPUTER-INTEGRATED MANUFACTURING 1989年第1期5卷 43-51页

作者： KIM, SH Knowledge Systems Program Laboratory for Manufacturing and Productivity Massachussetts Institute of Technology Cambridge MA 02139 U.S.A.

A theoretical framework for the analysis and synthesis of intelligent systems is presented. The basic models of automata theory and adaptive systems are highlighted, then extended and interpreted in the context of intelligent system design. In particular, the basic models are generalized to intelligent systems incorporating self-learning behavior. The utility of this approach is demonstrated by its use as a rigorous basis for (1) the discussion of information minimization in automatic systems, (2) the formal structure of adaptive systems and (3) implications for a general theory of intelligent systems.

The U.S. Navy relies heavily on advanced technology to carry out its missions. As a consequence, today's sailors are spending increasing amounts of time maintaining and repairing complex systems and equipment. In performing these duties, sailors depend on supporting technical documentation. As the complexity of systems and equipment grow, the volume and complexity of this technical documentation also increases. As a result, technical information, one of the Navy's critical resources, is simultaneously becoming more vital and more difficult to use. The Navy is meeting this challenge by exploring innovative approaches to the management of technical documentation. One example is the Paperless Ship Initiative, which employs optical disk technology as the primary means for document storage. Optical disks can store large volumes of technical information in a small space. One way to take advantage of this auto mated access is to make technical information more readily accessible and easier to use. As an example, a technical manual can be organized on an optical disk into discrete segments of text and indexed for fast retrieval by section, subsection, or paragraph. Furthermore, mechanisms can be developed which allow computer-supported links between logically related segments of the text. This style of interface allows a user to interact directly with the textual passages and to establish new organizational and referential links between them. This style of interface falls under the general category of hypertext (also known as linked text ). The combination of optical disk storage and hypertext offers new possibilities for improving access to large volumes of technical documentation while maintaining all of the advantages of traditional paper-based documentation. This paper begins with a discussion of the need for better technical documentation support. Alternatives that can fulfill this need are reviewed and the role of hypertext is described. The paper illustrates a sample

DESIGN AND MANUFACTURING ADVISOR FOR TURBINE DISKS

引用

ROBOTICS AND COMPUTER-INTEGRATED MANUFACTURING 1988年第3-4期4卷 585-592页

作者： KIM, SH HOM, S PARTHASARATHY, S Knowledge Systems Program M.I.T. Laboratory for Manufacturing and Productivity Cambridge Massachusetts 02139 U.S.A.

The design and manufacturing advisor (DMA) is a generic architecture for an expert system which assists in the process of product design. It integrates various parts of the production environment which affect the final product—such as fabrication, assembly, inspection and inventory. The design process can be partitioned into four stages: problem specification, feature specification, testing and generation. DMA facilitates the development of tractable designs, defined by the intersection of three spaces relating to specifications, features and productibility. The system consists of a domain-independent module and a domain-dependent module, each of which contains subcomponents; this modular structure facilitats system modification, expansion, and portability. The DMA has been validated by specializing the architecture to the design of gas-turbine disks for jet engines.
