Abstract

Limits of optimality in a generic two-degree of freedom control system is investigated. New relationships are introduced for the decomposition to identification and optimization errors in inverse stable and inverse unstable processes. In the inverse stable case these errors has a random, in the inverse unstable case systematic and random parts.
