Nine plenary papers were represented for the first day of the multiconference working.

The paper of S.N.Vassilyev, A.P.Kurdyukov (ICS RAS, Moscow), A.B.Kurzhanskiy (M.V.Lomono-sov MSU) "To 50-years of the I-st IFAC Congress" was devoted to Congress, which was held at Moscow from 27-th of June to 7-th of July, 1960, in M.V.Lomonosov MSU. Authors have presented the brief review of the IFAC initiation history; its objects and tasks; events, which were preceded to the Congress; the structure of IFAC co-ordinate and technical committes.

The Congress was opened by IFAC President A.M.Letov. Vice-president of IFAC professor G.Chessnat (USA), Vice-chairman of USSR Council of Ministers A.N.Kosygin, President of USSR AN academician A.N.Nesmeyanov, ChPR the head of delegation U-Gu-Yan, Professor R.Ol'denburg (USA) and professor E.Gereke (Switzerland) have made the greetings.

The Congress gathered 1190 participants from 29 countries and more than 1000 guests. Among the participants there were R.Kalman, M.Popov, M.Mesarovich, E.Djury, V.Streic, X.Rozenbrok, V.S.Kulebakin, B.N.Petrov, Ya.Z.Tsypkin, Yu.I.Neimark, A.I.Lurie and other well known scientists on control theory. In the work of Congress outstanding mathematicians A.N.Kolmogorov and L.S.Pontryagin have taken part. The Congress' motto was "To theory-practical using, to technical aids-maximal reliability, to equipment-maximal effectiveness". The Congress was of considerable importance for developing of control theory.

In the paper of A.A.Kurzhanskiy, A.B.Kurzhanskiy (M.V.Lomonosov MSU), P.Varaiya (University of California, Berkley) "Active control of transport net on the base of macromodel" the active control system of transport net was considered. The net is destined for control by streams on motor highways at regular and suddenly arising overloads. The authors note that traffic jams in the cities lead to long delays, high consumption of petrol and excessive pollution of environment. In the paper the system structure and its diagram of functioning were obtained. The central element of the system is "fast and reliable simulator". As a candidate of such kind simulator it was suggested the system Aurora Road Network Modeler. It is free programmed package for simulation car traffic on motor highways and city roads with light signal on cross-roads. The simulator work regimes were considered and the lines of further investigation in control of transport nets were formulated.

In the paper of B.V.Sokolov, R.M.Yusupov (SPII of RAS) and E.C.Tsivirko (The Committee on informatization and communication of S-Petersburg Government) "Analysis of the informational technologies on the control system effectiveness" it was undertaken an attempt to analyze the lines and influence informational technologies and informatization system on the processes and control systems of different nature. The authors have considered the state and the tendencies of development of the informational systems and also informational technologies in the control systems by activity cycle of informational and computer controlled systems. It has been proposed that the main tendency of development such class of the systems will be connected with the problem's solving of their comprehensive integration with future industrial and social-economic structures and corresponding control systems. For successful solving of this problem the authors consider that it is necessary to solve a number of methodical and industrial tasks. Such tasks are: formation and proof of the measure indices information system, design and ground of the structure of information regular measurement system, design and ground of the methods for analysis and synthesis of adaptive technologies at organization and realization processes of generation, registration, gathering, transmission, accumulation, storage and investigation of the people interaction with adaptive informational control systems, investigation of the such properties as self-configuration, self-service, fault-tolerance and others.

The paper of E.Ya.Rappoport (Samara State Technical University) "Control by macrovariables of the distributed parameter system" considers the methodology of transfer to the control by aggregative macrovariables which are formulated as some function of phase coordinates and desired parameters of feedback. The system synthesis task is removed to two-step organization of control algorithms that realize an attracting manifold. The phase trajectories go along this manifold to the steady state. The dynamic of macrovariables changing is described by stable extremals of a variable quadratic functional in phase space. The calculation of macrovariable total derivatives lead to the functional correlations for desired control algorithm determination.

In the paper of I.A.Kalyaev (SRI, MCS, SFU, Taganrog) "Strategy of group-control in distributed systems" it was considered control of the group of objects which are joined by a common goal. The examples of the group-control in living and nonliving nature were presented, the classification of the group-control was given. The advantages and disadvantages of the different strategies classes were considered. In the paper main attention was given to consideration of decentralized group-control. The author believes that this type of control is the most perspective in respect to minimization of time for acceptance of group solution and survival of distributed system. It is given the main information about cluster strategy which can be effectively used at control by big groups of objects, for example, by "clouds" of micro-robots. The pack strategy was considered also.

B.T.Polyak (ICS of RAS, Moscow) in the paper "Methods l₁-optimization at control and filtration" has considered l₁-approach using in discrete tasks of control. The author noted that as differentiated from the uninterrupted systems for the discrete ones the problems of existence and impulse character of solution are taken off. In the paper the main attention was converted to investigations of solution characteristics and to using numerical methods of the solutions getting. It was noted that the computer technique developing and the optimization methods has led to reconsideration traditional opinion on many statements of control and optimization tasks. Earlier quadratic criterions were widely used because it was possible to get analytical solution. Now the solution of optimization tasks with modulus functions does not present difficulties. The wide interest lies in using l₁-approach in the tasks of filtration. It is more preferred in compare with Kalman filter because of the assumption on disturbances normality in the motion equations is justified rarely.

In the paper of V.Ya.Raspopov (Tula SU, Tula, Russia) "Micromechanical gyroscopes and accelerometers in control systems by motion" strap down attitude control systems and navigation systems are considered. As inertial sensors for these systems the micromechanical gyroscopes and accelerometers are used. The results of the gyroscopes and the accelerometers errors analysis is presented. The influence of these errors on the accuracy of the attitude and navigation parameters defining is investigated.

In the paper of S.N.Grigor'ev (MSTU "Stankin") "The state and prospects of home-mode systems development of number programmed control by technological equipment" the state of the home-made systems development of number programmed control (NPC) is analyzed. It was noted that at present in Russia only 5% lathes and not more than 1% of blacksmith-press equipment have NPC. For comparison in USSR in 1990 these indices were 14% and 6% accordingly. The characteristics of modern foreign NPC by class "Hi-End" are given. It is noted that in Russia the same systems not produced and put out systems can not be as a base for creation systems by class "Hi-End" because of our systems architectural restrictions. The systems which are designed in MSTU "Stankin" for solution different tasks are described. They are the base main body for designing multifunctional system NPC. It is considered the prospects of development of home-made system by class "Hi-End".

In the paper of V.I.Gorodezkiy, A.V.Ivaschenko, O.V.Karasyov, P.O.Skobelev, R.M.Yusupov, A.V.Tsaryov (SPII of RAS, OOO "SPK Razumnyje Resheniya", Samara) a new platform for designing multi-agent systems was suggested. It was given the first applications of the platform for solving the tasks of control by resources in the different branches of industry. The examples are described among which there are multi-agent control systems by taxi, by airports ground service, by inside department's planning and others. It was considered the peculiarities of the suggested platform which is to provide making of industrial on-line multi-agent control systems by resources.
