Optimizing nonlinear adaptive control allocation [PDF]
Modeling, Identification and Control, 2006 A control-Lyapunov approach is used to develop an adaptive optimizing control allocation algorithm for over-actuated mechanical systems where the actuator model is affine in the uncertain parameters. Uniform global (asymptotic) stability is guaranteed by

Controlled invariance for nonlinear systems [PDF]
IEEE Transactions on Automatic Control, 1982 Necessary and sufficient conditions are derived for "(A, B)-invariance," called here controlled invariance, for nonlinear systems x˙ = f(x, u). The obtained results generalize and elucidate already known results about systems x˙ = A(x)-Σmi=1 uiBi(x). A new and direct differential geometric interpretation of the concept of controlled invariance and the ...

An Algorithm to Automatically Detect the Smale Horseshoes
Discrete Dynamics in Nature and Society, 2012 Smale horseshoes, curvilinear rectangles and their U-shaped images patterned on Smale's famous example, provide a rigorous way to study chaos in dynamical systems.

IET Control Theory & Applications, 2023 In this paper, finite‐time cluster synchronization (FTCS) in networks of nonidentical coupled dynamical systems is addressed by introducing a discontinuous interaction rule. This interaction rule overcomes the effect of heterogeneous dynamics among nodes.

SICE Journal of Control, Measurement, and System Integration, 2018 This paper presents a novel unified approach of controller design and identification for unknown input affine nonlinear systems. An issue with obtaining the best performance of optimal control is that identification errors degrade control performance ...

The Investigation of Nonlinear Polynomial Control Systems
Моделирование и анализ информационных систем, 2021 The paper considers methods for estimating stability using Lyapunov functions, which are used for nonlinear polynomial control systems. The apparatus of the Gro¨bner basis method is used to assess the stability of a dynamical system. A description of the
