Invariance and Identifiability in Adaptive Coordinate - Parametric Control

Abstract

The paper is concerned with control of plants whose dynamic features vary widely with time. Selfadjusting controllers are used in such plants. With broad ranges of dynamic responses, however, a selfadjusting controller may prove inadequate for control and purposeful modification of the plant design may prove necessary. The paper synthesizes algorithms for design of selfadjusting controllers and loops for change of the plant design parameters by using nonsearching selfadjusting model reference system; invariance and identifiability of the resultant structures are ascertained.
