Networked control systems (NCS) have recently received an increasing attention from the control systems community. One of the major problems in NCS is how to model the highly nonlinear terms caused by uncertain delays such as time-varying input delays. A straightforward solution is to employ polytopic approximations. In this paper we develop a novel method for creating discrete-time models for ...

Authors are requested to select key words from the following list. You may use plurals and adjectives for combinations like absolute pupillary response, centrifugal optic nerve, inter blobs, etc. If key words are needed which do not appear in this list, please underline them. For animal classification the Latin nomenclature should be used. p-mechanism A-scan a-wave aberration absolute absorptio...

We provide new designs for multivariable extremum seeking static maps with arbitrarily long time delays. allow different delays in each input channel and output delays, gradient- Newton-based frameworks. Our sequential predictor based approach provides an alternative to earlier prediction methods, leads where a dynamical extension eliminates the need distributed terms. source example illustrate...

This paper proposes an input/output interpretation of supervision of discrete event systems. New concepts must be introduced in order to describe the behavior of the closed-loop system of plant and supervisor subject to communication delays. This paper further characterizes the class of supervisors allowed under delays for the general case and for additional assumptions on the plant language.

The output-feedback control problem for nonlinear systems with state and input delays is addressed. Both state and input delays are allowed to be time-varying and uncertain. The class of systems considered consists of a nominal system of strictfeedback form as well as appended dynamics and inverse dynamics. A delay-independent robust adaptive feedback is designed based on our recent results on ...
