General Aspects of Control Theory
Abstract. In the conditions of a global information space, the special features of the formation of a social metasystem and its conversion into a new state are examined. The computer problems of the control paradigm globalization are discerned and investigated fr om the generic viewpoint. The axiomatics of the mathematically uniform field of computer information in the model of tree-type structures calculus is justified. An approach to the global control problems solution in the mathematically uniform field of computer information is formed.
Abstract. An approach to the problem of semantical information theory is considered. The approach is based on the application of an associative inductive inference system as an information receiver and enables to discern two information types: the database-forming information and the current topical information. A quantitative measure is defined for these two types of information.
Analysis and Design of Control Systems
Abstract. The duality of observability and controllability properties for nonlinear continuous and discrete dynamic systems is established.
Abstract. The digital dynamic discrete-time systems are considered wh ere admissible values of inputs and outputs are constrained by the fixed number of bit. The number of possible structures is evaluated and the computer simulation results are presented. The paper shows that proper asymptotic response may be belong to one three types: zero, constant, or periodic.
Abstract. The control of complex dynamic objects with uncertainties is discussed. New variable-structure adaptive control algorithms with paired and nonlinear deformable surfaces are offered. By an example of simple variable-structure adaptive systems, the paper shows that the approach proposed enables considerable improvement of system’s dynamic performance with significant reduction of energy consumed for zero-overshoot control.
Systems Analysis and Data Processing
Abstract. The paper offers a dialog system for multicriterion selection and adjustment of predictive models for epidemiological data analysis. The elaborated multicriterion description seeks to obtain a better quality of time series forecasting, thus allowing to formulate the forecasting problem as an optimization one. The applications of the approach to the selection and adjustment of predictive models for different diseases are demonstrated.
Control in Social and Economic Systems
Abstract. The paper examines developments in engineering and their impact on society from a post-structural perspective, focusing on social impact, especially on labor, and on the environmental impact of technology, particularly in terms of global increases in consumption. Displacement of labor is discussed in terms of growing underemployment as machine enhanced productivity evolves from production of tangible goods to skilled and professional work. Ethical questions need to be re-framed to be relevant to reflect the evolution of work structures. Current developments create a positive feedback loop with adverse consequences for socio-political and environmental systems. Some analysts believe our current social system has already become highly unstable.
Abstract. The paper offers model, methods, and a technology for investigating and controlling complex socio-economic systems as applied to solving some regional and federal problems of overcoming the system crisis and subsequent transition to sustainable development.
Abstract. A concept of cybercommunities formation as a natural phase in mankind evolution is discussed. Distinctive features of telecommunicational environment for innovation activities support related to this process are analyzed. The experience of the approach application to the scientific youth cybercommunity is expounded.
Problem-Oriented Control Systems
Abstract. An approach to security insurance design based on a complex security level estimation system is proposed. The problem of cost minimization for the achievement of the required complex estimate is formulated and solved.
Abstract. Design concepts of a computer-aided training system for control room operators of a chemical weapons destruction plant and the functionality of its software modules are considered.
Abstract. The possibility is shown and the description and solution methods of the volumetric planning problem based on the enterprise bookkeeping data are developed. The methods allow to solve the planning problems directly on specific enterprise data and to present the results in terms and concepts assumed in bookkeeping accounting. Formally, the planning problem is reduced to the well-known constrained optimization problem of a multivariable function that can be solved using the known techniques. In view of the problem’s linearity the LP methods are preferable.
Moving Objects Control
Abstract. Based on analysis results, A diagram of real-time expert system integrating with the existing testing complexes is offered. The tasks for an embedded expert system are determined and the hardware necessary for their implementation is outlined.
