Robust Stabilization by Linear Output Delay Feedback

Robust Stabilization by Linear Output Delay Feedback

The main result establishes that if a controller C (comprising of a linear feedback of the output and its derivatives) globally stabilizes a (nonlinear) plant P , then global stabilization of P can also be achieved by an output feedback controller C[h] where the output derivatives in C are replaced by an Euler approximation with sufficiently small delay h > 0. This is proved within the conceptu...

Robust global stabilization by means of discrete-delay output feedback

In this work, sufficient conditions for global stabilization of nonlinear uncertain systems by means of discrete-delay static output feedback are presented. Examples illustrate the efficiency of the proposed control strategy. © 2008 Elsevier B.V. All rights reserved.

Delay Effects on Static Output Feedback Stabilization

This paper addresses conditions for characterizing static output feedback controllers including delays for some proper transfer functions. The interest of such study is in controlling systems which can not be stabilized by the classical, nondelayed static output feedback, and its difficulty lies in computing delay intervals guaranteeing closed-loop stability, since for the same matrix gain, sta...

Stabilization of Linear Systems by Time - Delay Feedback Controls

The notion of r-stabilizability of linear autonomous systems is introduced. If the system [ A, B] is completely controllable and the spectrum of A is contained in the left half of the complex plane then the system is r-stabilizable for any r > 0. Finally, a one-dimensional case is discussed.
