Towards a performance theory of robust adaptive control

open access: yes, 2004
We consider standard robust adaptive control designs based on the dead-zone and projection modifications, and compare their performance w.r.t. a worst case transient cost functional penalising the L∞ norm of the output, control and control derivative. If

Robust Adaptive Backstepping Control Over Native Spaces

open access: yes
This paper presents the first robust adaptive backstepping control system for dynamical systems whose functional uncertainties are assumed to lie in a user-defined native space (also known as reproducing kernel Hilbert space).

A Performance Analysis of Two Approximate Adaptive Designs

open access: yes, 2005
The performance of function approximator based adaptive control designs may scale badly with approximator dimension [1]. For a simple system class, both projection based designs and multi-resolution approximation based designs have been shown to have ...

Adaptive backstepping control with estimation for the vibration isolation of buildings

open access: yes, 2012
A new adaptive backstepping controller with estimation for uncertain systems is presented in this study. The uncertainties are due to an unknown control coefficient and unknown or uncertain terms included in the system equations. The backstepping control

A novel 3-D jerk chaotic system with three quadratic nonlinearities and its adaptive control

open access: yesArchives of Control Sciences, 2016
This paper announces an eight-term novel 3-D jerk chaotic system with three quadratic nonlinearities. The phase portraits of the novel jerk chaotic system are displayed and the qualitative properties of the jerk system are described.

Adaptive backstepping and sliding mode control of a quadrotor

open access: yesJournal of the Brazilian Society of Mechanical Sciences and Engineering
Abstract This article proposes a simple robust adaptive control architecture with minimum parameter estimation laws for trajectory tracking of a quadrotor subjected to parametric variations and environmental disturbances. This simple control architecture aims to achieve highly accurate, robust, and fast trajectory tracking of the ...

Adaptive backstepping stabilization of nonlinear uncertain systems with quantized input signal

open access: yes, 2013
In this paper, we study a general class of strict feedback nonlinear systems, where the input signal takes quantized values. We consider a stabilization problem for nonlinear uncertain systems via adaptive backstepping approach. The control design is

Adaptive backstepping nonlinear control of bioprocesses

open access: yesIFAC Proceedings Volumes, 2004
Abstract This paper deals with the design of adaptive and non adaptive nonlinear controllers based on backstepping techniques applied to bioprocess models. Backstepping techniques are known to be appropriate in particular to handle the control of systems with relative degree higher than one.
