Bettering operation of dynamic systems by learning: A new control theory for servomechanism or mechatronics systems

Abstract: A new concept called "betterment process" is proposed for the purpose of giving a learning ability of autonomous construction of a better control input to a class of multi-input multi-output servomechanism or mechatronics systems such as mechanical robots. It is assumed that those dynamic systems can be operated repeatedly at low cost and in a relatively short time under invariant initial physical conditions, but the knowledge on precise description of their dynamics is not required. The betterment process is composed of a simple iteration rule that generates autonomously a present actuator input better than the previous one, provided a desired output response is given. The convergence of iteration is proved for a simple betterment process where the k+1th input is composed of the kth input plus an increment of the derivative error between the kth output response and given desired response. Discussions on potential applications of the proposed theory to controlling robots or other mechanical systems are presented together with future subjects to be investigated.

The IEEE Computer Society Model Program in Computer Science and Engineering

Abstract: core curriculum provides academic planners a guideline adaptable to a range of options. The computer field has undergone rapid technological changes over the last 30-35 vears. During this time a well-established academic discipline has evolved. This discipline has sarious names, but Nill be referred to here as comiiputer science and engineering. Model curricula recom-meindations for four-year undergraduate programs in the computer area have been reported in the past by the IEEE Coomputer Society, the Association of Computing NMachinery, 2 and the Cosine Committee. 3 These reports have been widely distributed and used bv educators from many parts of the world. The rapid pace of technological developments creates a need to update the CSE curricula in this field much more trequentlv than most other fields. In late 1981, for instance , the Educational Activities Board of the Computer Societv undertook to update the 1977 model curricula. These rapid technological developments, however, have secondarv effects on other aspects of a CSE program besides the curriculum. Namely student enrollments have increased , further straining program facultv and resource aspects of a program. In early 1982 the scope of the project was expanded to encompass all aspects of a program. A number of institutions have complete CSE programs. In some cases, programs have been established in independent departments, while in other cases new programs have been established within existing departments and operate in parallel with the host program. In some institutions, onIN partial CSE programs exist as options of programs such as electrical engineering. In 1978, the Accreditation Board for Engineering and Technology established ac-creditation criteria for programs in the computer area. ABET criteria establish minimal, acceptable levels for the various aspects of an academic program. The ABET criteria are stated in a sery general manner to allow for a wide variety of acceptable programs. However, the general nature of these stated criteria is also a cause of misinterpretation as to what the criteria actually require. Currently , there are over 25 accredited CSE programs, but manv more universities are expected to request accreditation. In the case of complete programs, the consensus opinion of a national group from the academic, industrial, and gos ernment sectors of the profession as to the breadth and depth of the computer area would be valuable viewpoints that the facultv could integrate with their own expertise and local constraints in revising and upgrading their curriculum. Established independent CSE programs …

Science and Engineering Design

Abstract: HE RISE OF modern engineering design was one of those epoch-making T developments that transform human history. But it was, and still is, little noticed or understood outside the engineering fraternity. One of the few persons who did understand the consequences of design was Alfred North Whitehead. In a famous passage from his influential Science and the Modern World , Whitehead noted that "the greatest invention of the nineteenth century was the invention of the method of invention."' Quite often, this "invention" has been construed to be science itself. Actually, it is clear that Whitehead had in mind not science itself, but the linking of engineering design with science, quite another matter. For, following this just-quoted famous statement, Whitehead qualified it:

Scarce programs: From power engineering and electromagnetics to telecommunications and instrumentation, specialized programs are in short supply

Abstract: A collection of short articles describes seven programs that are either missing or in short supply. These are: power engineering, electromagnetics, instrumentation, telecommunications, manufacturing, communicating (oral, written, and visual), and societal awareness.

Future Trend of Technological Research and Development and Its Potential Impact on Society

Abstract: Future technological research and development will be concentrated in the following three areas: (1) electronics, (2) new materials, and (3) biotechnology. Electronics will include the following items: micro-electronics (MS) centering on semiconductor circuit integration technology, mechatronics, (a combination of electronics with precision machinery engineering) and Optronics, (a combination of electronics with optical technology, such as laser beams). Typical mechatronic products includes NC machine tools, machining centers (MC), robots, and flexible manufacturing systems (FMS), etc. in the factory automation (FA) sector; small business computers, word processors, electronic photocopiers, and facsimile machines in the office automation (OA) sector; computer aided design (CAD) in the engineering office sector; and video tape recorders (VTR), video disks, and digital audio equipment, in the electronic video and audio sector. In addition, mechatronics technology has been applied to the automobile as well as to electronic games electronic desk-top calculators, digital watches, etc. Opto-electronics include optical fiber telecommunication, laser beam machining and surgical operation using laser equipment, solar battery, etc. In the biomedical field, electronics is essential in X-ray CT (computer tomography), supersonic CT, NMR, position emission scanners, etc. Typical new materials include fine ceramics, essential materials for electronics, carbon fiber, and a variety of composite materials, etc. Biotechnology includes gene manipulation, cellular fusion and in the broad sense, various artificial organs.

The Instructional Systems Development Model and Systems Engineering

Abstract: Two implicit perspectives governing the organization of human performance have evolved within the training community, leading to two different approaches to the systematic development of performance-based training. These are identified here as the Instructional Systems Development (ISD) approach, and the Systems Engineering approach. Both employ similar procedures with the exception that the ISD approach relies on an initial job-oriented analysis; the Systems Engineering approach relies on a functional systems analysis. This difference affects the scope and organization of the data. Resulting training programs and materials are more suited to some applications than to others. This paper presents a conceptual framework illustrating the relationship and argues that the two approaches are theoretically equivalent. Within this framework practical training development implications, problems, and benefits are discussed.
