Stability and grudeness conditions for a single-channel invariant arbitrary-order system

Abstract: Conditions are studied under which stability is obtained and errors are reduced in a single-channel invariant stabilization system for a linear arbitrary-order process with parameter deviations (in particular, with small pure delays and inertias). These conditions are shown to be fairly rigid; in particular, the controller input unit should incorporate differential of an order equal to or lower by a unity than that of the process. The result enables estimating the practicability of controller as «loop with an infinite gain» and the difficulties of using it.
