A new class of Lyapunov uniformly globally asymptotically stable (UGAS) protocols in
networked control systems (NCS) is considered. It is shown that if the controller is designed …

Traditionally, the design of extremum seeking algorithm treats the system as essentially a
black-box, which for many applications means disregarding known information about the …

The persistence of excitation of signals generated by time-invariant, autonomous, linear, and
nonlinear systems is studied using a geometric approach. A rank condition is shown to be …

Model reference adaptive control is a well-understood and popular method used in the case
when the plant's constant parameters are unknown and must be identified. The related …

This paper presents a practically applicable characterization of uniform (global) asymptotic
stability (UAS and UGAS) for general nonlinear time-varying systems, under certain output …

We study the stability properties of a class of time-varying non-linear systems. We assume
that non-strict input-to-state stable (ISS) Lyapunov functions for our systems are given and …

In this work, a generalized adaptive scheme for the global motion control of robot
manipulators with constrained inputs is proposed. It gives rise to various families of bounded …

We address the problem of controlled synchronization of a class of uncertain chaotic
systems. Our approach follows techniques of adaptive tracking control and identification of …

The persistence of excitation (PE) condition is sufficient to ensure parameter convergence in
adaptive estimation problems. Recent results on adaptive estimation in reproducing kernel …

We propose a method for redesigning adaptive observers for nonlinear systems. The
redesign uses an adaptive law that is based on delayed observers. This increases the …
