ADAPTIVE-CONTROL SYSTEMS WITH AUGMENTED ERRORS

This survey is devoted to the problem of adaptive control with a reference model of a linear steady-state object without measuring the derivatives of an input and an output signal. Primary attention is given to the problem of augmentation of a tracking error. The known augmentation systems are described, a comparative analysis of these systems and their unified (generalized) structure is made, and the problems of stable closed adaptive systems with augmented errors are considered. The subject of this paper is restricted to the class of continuous deterministic systems.
