The C4ISR Architecture Framework document issued by the department of Defense specifies three views of an information architecture and defines a set of products that describe each view. These architecture views are to serve as the basis for C4ISR system development and acquisition. The Framework does not provide a process for architecture design. In this paper, information architectures are described in the context of Structured Analysis, and then the architecture views of the Framework and the related products are interpreted in that context. A methodology for architecture design is developed that is then implemented using Structured Analysis and object orientation in two companion papers. © 2000 John Wiley & Sons, Inc.

This paper present a new effective algorithm for the optimal realization of state estimate feedback controller structures for discrete time systems subject to finite-word-length constraints. The problem is formulated as a nonlinear programming to provide an easy and efficient optimization tool to solve such a complex problem. Simulation results of the optimum realizations of state estimate feedback controller structures are presented to illustrate the effectiveness of the proposed strategy.

Industrial applications are characterised by increasing complexity of distributed control systems. The control system is compound of intelligent sensors and actuators, micro-controllers, PLC's, PC's and workstations in industrial and computer nets and operating systems. In such distributed control systems is possible effectively using multi-agent architecture, where agents co-operate under a structured organisation, using the scenario recognition approach. The typical application is the transport of mass and/or energy by large pipeline systems of great complexity undergoes a number of technician and economical constraints. This involves the problem of a dynamic optimal control of distribution systems. In this paper, the optimal control of steam and hot water distribution in the large pipeline network is discussed.

The model of mobile robot is designed and performed using the three-wheels principle. Each of wheels is derived through a separate electrical motor-drive. The actual motion trajectory is defined by the actual turning frequency of motors. The motor-drivers are controlled using the microprocessor unit calculating the motion control signals for each of one. Global driving signal is calculated and transmitted through the HF radio communication equipment using the central PC self-learning control fuzzy oriented system. Distributed robot’s control system is performed using the MOTOROLA M68HC11 family equipment.

Factorization method for multiple perspective views via iterative depth estimation

This paper proposes a factorization method that reconstructs camera motion and scene shape based on the matching of multiple images under the condition that the camera captures a perspective view. Starting from the affine projection camera model, the projection depth is iteratively estimated until the measurement matrix has rank 4. Then, the obtained measurement matrix is factorized to restore the three-dimensional information of the scene in the projection space. This approach eliminates noise sensitive processes, such as the calculation of the fundamental matrix, that are required in the factorization for the conventional perspective projection image, and a stable reconstruction is realized. Furthermore, the metric constraint in the conventional affine model is extended, and the metric constraint in the perspective projection condition is derived. It is shown that the reconstruction in Euclidean space is realized if the internal parameters of the camera are given.

The H_∞ almost disturbance decoupling problem is considered. In this paper, a nonlinear design is proposed to find a state feedback controller for bilinear systems. The closed-loop system is internally stable and achieves disturbance attenuation in nonlinear H_∞ sense. We defined a special form of Lyapunov function, which is constructed in terms of one or a set of positive definite constant matrices. If, except of the origin of system, the corresponding polynomial of the positive definite matrix (or several polynomials relevant to the positive definite constant matrices) has (have) no zero on a given subset of state space, then we can construct a controller to solve our problem. It is found that the controller structure could be complicated, but is feasible in computation and may require optimization technique to search the solution. We consider both SIMO and MIMO cases with illustrated examples.

Decomposing dynamical systems in terms of orthogonal expansions enables the modelling/approximation of a system with a finite length expansion. By flexibly tuning the basis functions to underlying system characteristics, the rate of convergence of these expansions can be drastically increased, leading to highly accurate models (small bias) being represented by few parameters (small variance). Additionally algorithmic and numerical aspects are favourable. A recently developed general theory for basis construction will be presented, that is a generalization of the classical Laguerre theory. The basis functions are applied in problems of identification, approximation, realization, uncertainty modelling, and adaptive filtering, particularly exploiting the property that basis function models are linearly parametrized. Besides powerful algorithms, they also provide useful analysis tools for understanding the underlying identification/approximation algorithms.

In this paper, the potential applications of Fraser-Hipel-Kilgur methodology for conflict modelling and resolution, based on the theory of non-cooperative games theory, to the modelling analysis of Balkan conflicts is exploerd through the case study on the conflicting interests over R. Macedonia by the end of the twentieth century. Particular attention was devoted to the use of its advanced variant based on theory of digraphs and adjacent reachability matrices. The graph form takes game outcomes rather than individual decisions as the basic units for modelling conflicts, described in sufficient detail. A number of solution concepts can be formulated and employed for both two-player and multi-player games, the latter being of primary interst in here. The taxonomy of graph based solution concepts of the original methodology has been employed to account for certain anticipation horizon by each of the players. This methodology makes essential use of the fundamental axioms of game theory defined by posulates of the individual rationality, the players inertia, the limited-move stability, and the minimum effect for the opponents.

This paper proposes a genetic-based algorithm for surface reconstruction of three-dimension (3-D) objects from a group of contours representing its section plane lines. The algorithm can optimize the triangulation of the surface of 3-D objects with a multi-objective optimization function to meet the needs of a wide range of applications. Further, a new crossover operator for triangulation and a new 3-D quadrilateral mutation operator are also introduced.

The present paper deals with the production of Saccharomyces cerevisiae, described by a sixth order nonlinear state space model. The control objective is to ensure the process stability and desirable specifications in the presence of disturbances and lack of reliable state measurements. First, the model of the process and its properties are presented. Next the ability of multi-layer Neural Networks to act as reliable emulators of the system dynamics is tested by simulation results and a training strategy is proposed to improve their performance. Finally, a non-linear adaptive observer is designed by means of artificial neural networks. © 1999 EUCA.
