Minimax positional control of identification in nonlinear multi-step systems

In a range of multi-step systems described by nonlinear vector difference equations and identified by minimax positional feedback control only the set of possible initial states and the history of the control action and the signal containing incomplete information on the system are assumed to be available. A parameter is identified which characterizes the unmonitorable action of a constrained perturbation in the equation which describes the system dynamics. An algorithm for development of an information set of the process and a backward sequence of positional identification control are proposed.
