ABSTRAKT

We consider the problem of control of objects under action of bounded additive perturbations, for parameters of which rough a priori multiple estimates are given. We ascertained contradictoriness of requirements, which are put on selection of control on solving problems of parametric identification and problems of object motion control. We showed that strict resolving of this problem is possible on statement of the problem of synthesis as a problem of minimum of functional computed along trajectory of object motion. Here for obtaining the guaranteed result the problem of synthesis is introduced as minimax problem with mixed constraints, which numerical solution is connected with considerable computational expenditures. Therefore, we suggested the method of synthesis of suboptimal control on the basis of compromise between the mentioned contradictory requirements to control.
