In many mechanical systems, the tracking control is one of the most important issues. Therefore for the unstable system subject to actuator saturation, the domain of the initial states corresponding to an arbitrary reference signal, within which tracking condition can be achieved, is interesting to be considered. In this paper, an approximate tracking domain is derived analytically. First in Theorem 1, for simple case, it is constructed by using the partial Lyapunov function and the absolute stability theory. In the following Theorems 2 and 3, a new idea is used to obtain larger domains. Finally in the last section, a simple numerical example is given.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.

Time-varying electric loads, fluctuating around their nominal point, cause fluctuations also of current and power. The mean phasors of current and complex power differ from their nominal values, which results in a deflection of mean power input. A transformation to a time-invariant equivalent circuit is introduced representing the mean values of voltage, current and power. The variances on the other hand contribute equations for a second phenomenon of fluctuating lends: the generation of disturbances in the power supply system. Results for both phenomena are derived for single-phase lends, validated by Monte-Carlo simulations, and generalized to three important kinds of three-phase bonds. Measured data from an electric arc furnace illustrate the application of ideas.

A methodology is presented to determine the optimal sequence of capacitor switching in a power system for maintaining a desirable voltage profile over a load cycle. In the first part of the algorithm, the set point voltage of the generators are determined by a non-linear secondary voltage controller that is emulated by a feedforward neural network. In the second part, these generator voltages constitute the starting point to determine the optimal switching of capacitors by using a dynamic program solver. The algorithm was validated on an IEEE 57 bus test system with the individual loads varying non-uniformly between 50% and 110% of their base values.

In this paper it is discussed a new configuration for a fiber-optic current sensor (FOCS) which increases the linearity range of the device without decreasing its sensitivity exploiting an appropriate feedback loop;in this way the whole system behaves as a ''null-detector''. Moreover, the effect of bending-induced linear birefringence is explicitly taken into account in the design and optimization of the sensor. It is shown that the response of the experimental apparatus is practically temperature independent and that its bandwidth gets values higher than 1 MHz.

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.

A distributed diagnosis system combining Immune Network (IN) and Learning Vector Quantization (LVQ) for detecting fault sensors accurately in industrial plants is proposed. It has two execution modes, namely, its training mode where LVQ extracts correlation between each two sensors from their outputs when they work properly, and its diagnosis mode, where LVQ contributes to testing each two sensors using the extracted correlation, while IN contributes to determining fault sensors by integrating these local testing results obtained from LVQ. Discussed here is how to improve diagnosis capability of the developed system. It is shown that the thresholds can be determined effectively by the constraint that the hyperregion corresponding to the normal sensor outputs in each quantization vector space is a single region. Diagnosis capability of the developed system is evaluated using a prototype system for detecting fault sensors of a reheating furnace plant. With the proposed method, abnormal sensors, such as aged deteriorated ones, which have been difficult to be detected only by checking each output of sensor independently, are possible to be specified.

作者： Saito, T Aida, H Kim, B Aoki, T Faculty of Engineering the University of Tokyo Tokyo Japan 113 Byung-suk Kim:graduated in 1991 from the Department of Electrical Engineering Seoul University Korea and received his Master's degree in 1994 from the University of Tokyo where he is currently in the doctoral program. He is engaged in research on access control in ultrahigh-speed LAN.

With the advent of broadband integrated services digital network (B-ISDN), there is the increasing need for high-speed multimedia systems also in the area of local area networks (LANs). It is obvious that the conventional systems such as CSMA/CD or token ring cannot cope with those requirements. At present, several new access control methods are proposed for slotted ring (or bus) LANs suited to transmission rates above 155 Mbps. This paper reviews the characteristics of those methods in a systematic way and proposes a new access control method called distributed reset algorithm (DRA). DRA can provide high throughput while maintaining the almost strict access fairness by using a new control called ''access bit control'' in addition to the already known window control.

Recently, the V/F control drive system of the induction motor has been applied widely to the drive of compressors, pumps, etc., because it is very simple and basically requires no speed sensors. However, if the V/F controlled induction motor drives a pulsating load such as the compressors, the rotational speed of the motors is fluctuated considerably and the motor frame vibrates due to the pulsating load torque. When frequency of the torque pulsation is especially close to the resonant frequency of the mechanical system, large vibration and acoustic noise are produced. In this paper the authors propose a method to reduce the vibration of the V/F controlled induction motor with a fluctuated load by repetitive control using an acceleration sensor. The acceleration sensor is easy to install on the motor or load frame. The repetitive control is considered effective for reduction of the vibration, as the load torque varies periodically. Effectiveness of the proposed method is confirmed by approximate analysis and experiments.

Although brushless resolvers have been used widely as angular position transducers, they are expensive due to their intricate construction, involving a rotary transformer to supply the exciting coils wound on the rotor poles with the current. It is shown theoretically in this paper that the resolver without rotary transformer or brushes can be realized by simple construction, which consists of the stator core with both 4-poles exciting windings and 2-poles output ones and the rotor core carrying no windings. In this resolver the rotor core has minimum gap at one side and a maximum gap at another side of the diameter. It is characterized by an outer surface form that makes the fluctuation part of gap permeance very in proportion to cos theta, where theta represents the angular position of a point in the air gap with respect to the origin on the rotor, the point of minimum air gap. The method determining the rotor form to embody the afore-mentioned gap permeance variation is also shown. It has been confirmed not only by simulation but also experiment that the 2-phase output voltages of a model designed based on the theory have sinusoidal waveforms with very small harmonic contents. Moreover, the rotor position detected by processing the output voltages through the conventional resolver/digital converter was within acceptable engineering accuracy.
