.. (. ) - () , (« -»). THE MODELING OF DISCRETE CONTROL SYSTEM WITH DOUBLE-TIME-SCALE Stepanchenko O.V. (Kamyshin city, Volgograd region) The issue deals with the algorithms design for the discrete plants with multi-rate state variables which may be separated to the subprocesses with low and fast modes correspondingly. The control algorithm synthesis is based on the two- time- scale control method. The results of DC double feeding electric driver illustrate the developed techniques. The problems of detection of the multi-rate effects presence are discussed as well. , ( , ) .

(Kamyshin city, Volgograd region) The issue deals with the selection algorithm synthesis of the computing service of the heterogeneous distributed computing system. The algorithm bases on the statistical data processing and fragmentation of subtasks in mandatory and secondary subtasks. The minimizing error function formulates in the work. The research results of algorithm for various parameters of computing system are also presented. , , ­ , , . 13
