The realistic and accurate simulation of complex systems demands a high computing power. This gave rise to the concept of distributed interactive simulation, based on a network of simulation facilities. This simulation concept eliminates the use of a central server, thus reducing the simulation latency. In this paper, the concept is extended, using standard concepts of distributed computing, to the simulation of continuous processes in a thermal power plant comprising of linear and nonlinear elements.

A concept for implementation of a colony of cooperative autonomous agents is under development. This concept enables useful and productive work to be accomplished by adaptable and dynamic autonomous agents in real-time and real-world environments. Three primary issues of cooperative autonomous mobile agents are addressed being interaction, management and sustainability. The focus of this paper is the issue of interaction within a colony of cooperative agents while the issues of management and sustainability are scheduled for future research. The view of the agents as a colony is due to their number and the use of agent support structures. A colony of agents has a defined base of operations consisting of relatively static agents while also containing a number of mobile agents.

In our paper we present a complete overview of a reliability control module for an electro-mechanical dice gambling machine based on computer vision principles. We particularly discuss the fundamental, heavily utilized function of color difference, which forms a basis for fast, efficient and parameterized chroma-key applications. We also explain the dice location estimation solution and the final template matching phase of number detection. In the conclusion we discuss some issues and problems which are still left open but should be solved by the project team.

In this paper we give some basic principles of fuzzy neural computing using synaptic and somatic operations. We first briefly review the neural systems based upon the conventional algebraic synaptic (confluence) and somatic (aggregation) operations. Then we provide a detailed neuronal morphology based upon fuzzy logic and its generalization in the form of T-operators. For such fuzzy logic based neurons, we then develop the learning and adaptation algorithm.

An attempt has been made in the present work to improve the dynamic and steady state performances of the vector controlled induction motor (IM) drives. Input-output linearization and decoupling technique based on the concepts of differential geometry, has been used to decouple the speed, or torque from flux. Optimal proportional-integral (P-I) controllers in flux and speed loops are designed to obtain desired dynamic and steady state responses. A new rotor flux observer has been designed to estimate the flux at all speeds. Simulation results show that the performance of the drive system with the designed controller is comparable to that with vector controller and the proposed drive system is more flexible.

In computing of transformer losses, it is assumed that source voltage is sinusoidal and load impedance is linear. For the four operating modes chosen, non(sinusoidal) source voltage and non(linear) load impedance, core losses and windings losses of the transformer are computed using on-line measurements of the primary and secondary sides. The results are presented and compared in this paper with the experimental results of the active losses on the transformer, on the different operation modes. Active losses have been obtained on both the resistance of the core (R/sub fen/) and winding resistances (R/sub 1n/ and R/sub 2n/). These active losses have been obtained considering maximum harmonic amplitude, maximum harmonic order, loading factor and loading time.

The paper presents the design of spatial control system of a large pressurized heavy water reactor (PHWR) with the constraint that the closed loop system be stable even if one output sensor has failed. Linear state models are obtained corresponding to the normal operating condition and different failure modes of the reactor. Each model is found to possess two time scale property. Application of a standard singular perturbation approach decouples the fast varying modes which are ignored to eliminate the stiffness. Thus a reduced model is obtained for each operating mode of the reactor. Convex programming is used to search for an output injection gain which stabilizes all reduced models simultaneously. This output injection gain is then realized simultaneously in all operating modes by a controller based on periodic output feedback.

This paper addresses the problem of determining H/sub /spl infin// optimal output feedback controllers for a large class of partially observed nonlinear systems. With an eye toward digital implementation, the authors' approach to implementing H/sub /spl infin// output feedback controllers has emphasized issues like reasonable computational complexity, knowledge of observable quantities only, and implementability in finite time. Examples have been provided to investigate the robustness properties of the controllers we have developed. Through direct simulation, the authors have demonstrated that the controller has been observed to be locally stabilizing and robust to noise for systems with even a large degree of nonlinearity.

A drag plate single sided linear induction motor (DP-SLIM) has been investigated. The Fourier transform model has been developed considering saturation and skin effect in the back iron. The flux dependent relative permeability of back iron that is required in the Fourier transform model has been obtained using FEM analysis. Performance characteristics at slip and at slip frequency have been reported for composite secondary, multi layer and drag plate SLIMs. The purpose of this paper is to analyze DP-SLIM from the viewpoint of its suitability for different applications.
