L1-Adaptive Control: Stability, Robustness, and Interpretations.

IEEE Trans. Autom. Control., 2014
An adaptive control design approach that involves the insertion of a strictly proper stable filter at the input of standard Model Reference Adaptive Control (MRAC) schemes has been proposed in the recent years. This approach was given the name L1-Adaptive Control (L1-AC) due to the L1 bounds obtained for various signals.

Adaptive Robust Stabilization of a Flexible Timoshenko Manipulator

2019 IEEE 4th International Conference on Advanced Robotics and Mechatronics (ICARM), 2019
This paper investigates an issue on the development of a vibration suppression scheme for stabilizing a flexible Timoshenko manipulator with time-varying disturbances and uncertain system parameters. In order to cope with the parametric uncertainties, mitigate the vibration, and realize the angle tracking of the manipulator, the boundary robust ...

Adaptive robust control (convergence, stability and performance)

1986 25th IEEE Conference on Decision and Control, 1986
The contributions of this paper are in two main areas. The first is an "integrated" approach to the development of a practical adaptive control algorithm. In particular, we bring many existing ideas together and explore the effect of various design parameters available to a user. We also extend the theory in the following areas: we show how the problem

Robust adaptive control: stability and asymptotic performance

IEEE Transactions on Automatic Control, 1992
Summary: This paper provides robust stability and asymptotic performance results for adaptive control in the presence of both compact real parametric uncertainty and frequency-weighted bounded unstructured uncertainty. It is shown that a class of parameter adaptive control systems is robustly stable. Furthermore, the asymptotic robust performance bound

ROBUST STABILITY CONDITIONS FOR ADAPTIVE CONTROL SYSTEMS

IFAC Proceedings Volumes, 1990
Abstract Robustness conditions for adaptive control system will be derived in the forms of usual robust control criteria (Owens and Chotai 1982) and slow variation or closeness assumptions. It will be shown that slow variation will be true if the closed-loop adaptive system is stable in l∞ sense.

Adaptive Robust Simultaneous Stabilization of Two Dynamic Positioning Vessels Based on a Port-Controlled Hamiltonian (PCH) Model

Energies, 2019
In this paper, the adaptive robust simultaneous stabilization problem of two ships is studied. Firstly, the water surface three-degree-of-freedom ship models are transformed into port-controlled Hamiltonian (PCH) models.

Adaptive tracking with robust stability

Proceedings of 32nd IEEE Conference on Decision and Control, 2002
We address adaptive tracking for nonlinear systems in 'observer canonical form'. We present control algorithms that combine the attractive features of recent adaptive algorithms with algorithms producing robust stability. This yields regressors which depend only the desired trajectory. >

Stability and robustness of fuzzy adaptive control of nonlinear systems

Applied Soft Computing, 2011
In this paper, we propose a new approach that guarantees the stability and robustness of an adaptive control law of a nonlinear system. The control diagram proposed contains a Takagi-Sugeno-Kang fuzzy controller (TSK-FC) and a training block allowing the online adaptation of the FC parameters. The adaptation algorithm used is based on the gradient with

Robust adaptive fuzzy logic power system stabilizer

Expert Systems with Applications, 2009
This paper introduces a robust adaptive fuzzy controller as a power system stabilizer (RFPSS) used to damp inter-area modes of oscillation following disturbances in power systems. In contrast to the IEEE standard multi-band power system stabilizer (MB-PSS), robust adaptive fuzzy-based stabilizers are more efficient because they cope with oscillations ...

Robust adaptive stabilization of flexible joint manipulators

Proceedings, 1989 International Conference on Robotics and Automation, 2003
A robust nonlinear adaptive control strategy is proposed to stabilize a robot manipulator subject to parametric and dynamic uncertainties. This is accomplished by utilizing state feedback and applying a control space transformation to a reduced-order model without parametric uncertainty.
