The book is concerned with the problems of dynamic systems control in conditions of uncertainty caused by the lack of adequate a priori data on control objects' properties. Its special feature is the use of a priori estimates of indeter- mined quantities on the form of sets. A unique method of ad- aptive control systems construction is described. A con- structional algorithm for solving parametric identification problems is suggested which allows guaranteed estimate to be received in the form of some set. The application of game approach tothe statement and solution of control synthesis...
