Robust stabilization of nonlinear object with SDC-parameterization

Afavasiev V.N., Titov D.V.

Abstract

Since the mid-90's, State-Dependent Riccati Inequality (SDRI) strategies have emerged as general design methods that provide a systematic and effective means of designing nonlinear controllers for a robust stabilization. In this paper, a new expression of free parameters to completely express the SDC form is proposed. This form is using to design linear robust model of nonlinear system and then to synthesis the controller with constant parameters. Finally, example to verify the advantage method is given.

The parallel realization of genetic algorithm on the base of network operator method for the task of two-tier inverted pendulum stabilisation Problem

Kulakov B.B., Zharkova A.S., Kazaryan K.E.

Abstract

It is considered a problem of two-tired inverted pendulum stabilization. Pareto-region for two functional is found by using network operator and parallel realization of genetic algorithm. Every point of that region gives a solution - state vector feedback control function. It is presented simulation results for one point of Pareto-region.

Multi criteria optimization of mechatronic system based on equilibrium-arbitrary compromise

Vaganyan A.A., Voronov E.M.

Abstract

This article considers a multiply connected mechatronic system of the telescope drive that consists of three subsystems - mechanical, executive and computer in conditions of structural inconsistency and uncertainty. 2-step algorithm of multi criteria optimization based on equilibrium-arbitrary compromise is used to calculate parameters of this system. This algorithm is based on optimization control methods of multi object multi criteria systems and stable efficient decisions and compromises.

Optimal control of multi-object multi-criteria systems, structural synthesis and hierarchical equilibration in intellectual control systems

Pupkov K.A., Voronov E.M., Karpunin A.A.

Abstract

Methodology of optimization of structural and functional complex control systems in typical form of multi-level hierarchical structure with multi-subsystem multi-criteria systems of regulation, control and decision making as a level is proposed. Methods of structural synthesis of optimal functional and technical habits of hierarchical distributed control system are formed within this framework. Definition of generalized control of multilevel automated control system is given. Procedure of optimization of the generalized control on the basis of generalization and algorithmization of hierarchical equilibrium in multilevel systems is developed. Results of use of approaches in problems under conditions of initial structural inconsistency, conflict situation and uncertainty are given.

Comparative Analyses of Russian and Western Top-Management

Alekseenko V.B., Ivanova T.B.

Abstract

To start innovation and modernization Russia needs to research and find out characteristics and special features of its CEO and either to learn or reject the Western experience. The main difference between Russian and Western management lies in their formation which determines their approaches to business activity. Russians have been concentrating their efforts on destruction of the previous values and basis, while Western management has been doing its best in business and welfare creation.
