An adaptive controller for nonlinear, linearly parameterized systems is presented. The new
features introduced in the design are:(1) parameter estimation is performed on the scalar …

A new design procedure is developed for adaptive output-feedback control of nonlinear
systems. The procedure guarantees boundedness even without adaptation and without …

Presents a direct adaptive tracking control scheme for nonlinear systems that do not have a
well defined relative degree and are not feedback linearizable. This technique uses …

This paper presents an adaptive control scheme for nonlinear systems that violates some of
the common regularity and structural conditions of current nonlinear adaptive schemes such …

The authors consider how to make a nonlinear control law adaptive. Assuming that the
uncertainties interfere linearly, they answer this question for a certain class of systems. In …

The authors present an indirect model-reference adaptive control scheme, which requires
only output measurement, for SISO full-linearizable minimum-phase nonlinear systems. The …

We present a new approach to adaptive nonlinear control based on a complete controller-
identifier separation which has long been a goal in adaptive system design. In this approach …

A description is given of a general input-output approach that can be used in the analysis
and design of adaptive control systems. The effectiveness of this approach is demonstrated …

This paper presents a stabilizing adaptive controller for a nonlinear system depending
affinely on some unknown parameters. We assume only this system is feedback stabilizable …

An approach to adaptive control of linear systems is presented. It foregoes the traditional
certainty-equivalence concept, and treats the control of linear plants with unknown …
