Barrier-Critic Adaptive Robust Control of Nonzero-Sum Differential Games for Uncertain Nonlinear Systems With State Constraints

IEEE Transactions on Systems, Man & Cybernetics. Systems
In this article, for the nonzero-sum (NZS) differential games problem of uncertain nonlinear systems with state constraints, an adaptive robust stabilization scheme based on the control barrier function (CBF) is presented under the influence of random ...

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

Adaptive Robust Control for Stochastic Systems With Unknown Interconnections

IEEE transactions on fuzzy systems, 2021
This article considers the decentralized stabilization problem of stochastic interconnected systems. The considered stochastic systems simultaneously contain unknown interconnections, power integrator dynamics, and time-varying delays.

Robust adaptive stabilizer for nominally stabilizable discrete plants

Proceedings of the 2003 American Control Conference, 2003., 2004
This paper presents an indirect adaptive control scheme for discrete linear time-invariant nominally nonnecessarily controllable and stabilizable systems. The scheme is a pole- placement type without requiring the plant inverse stability assumption. The adaptive stabilizability and the robustness of this system under the presence of unmodeled dynamics ...

Robust stability analysis of adaptation algorithms for single perceptron

IEEE Transactions on Neural Networks, 1991
The problem of robust stability and convergence of learning parameters of adaptation algorithms in a noisy environment for the single preceptron is addressed. The case in which the same input pattern is presented in the adaptation cycle is analyzed. The algorithm proposed is of the Widrow-Hoff type.

Adaptive Event-Triggered Prescribed-Time Stabilization of Uncertain Nonlinear Systems With Asymmetric Time-Varying Output Constraint

IEEE Transactions on Automatic Control
This article aims to solve two intricate problems in nonlinear control: 1) the singularity caused by driving the control to infinity at the prescribed time and 2) the stabilization via adaptive event-triggered feedback for a class of uncertain nonlinear ...

ROBUSTNESS OF MULTIVARIABLE NON-LINEAR ADAPTIVE FEEDBACK STABILIZATION

IFAC Proceedings Volumes, 1983
Abstract Here considered is the stabilizing property of the adaptive nonlinear dynamic feedback control proposed in (Hmamed and Radouane, 1983) for multivariable systems in the presence of uncertainty. A multivariable system is decomposed into a set of single-input subsystems and the second Luenberger canonical form is obtained.

Stability, robustness, and performance issues in second level adaptation

2014 American Control Conference, 2014
A new approach, described as second level adaptation, was introduced in [1] for the control of unknown linear time-invariant plants using multiple identification models. If θ p ∈ R n , the unknown parameter vector of an LTI system lies in the convex hull P(t 0 ) of (n+1) vectors θ i (t 0 ) (initial values of adaptive vectors) in parameter ...

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.

Adaptive robust stabilization of dynamic nonholonomic chained systems

Journal of Robotic Systems, 2001
AbstractIn this article, the stabilization problem is investigated for dynamic nonholonomic systems with unknown inertia parameters and disturbances. First, to facilitate control system design, the nonholonomic kinematic subsystem is transformed into a skew‐symmetric form and the properties of the overall systems are discussed.
