IET Control Theory & Applications, 2023 This paper investigates the coordinated behaviour of the multiple Euler–Lagrange systems under diverse interactions with time delays. Specially, in the case of undirected interconnection, the proportional plus damping control strategy is proposed and the

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

Controllability of nonlinear systems
Journal of Differential Equations, 1972 Discussion of the controllability of nonlinear systems described by the equation dx/dt - F(x,u). Concepts formulated by Chow (1939) and Lobry (1970) are applied to establish criteria for F and its derivatives to obtain qualitative information on sets which can be obtained from x which denotes a variable of state in an arbitrary, real, analytical ...

Analysis, Synchronization, and Robotic Application of a Modified Hyperjerk Chaotic System
Complexity, 2020 In this work, a novel hyperjerk system, with hyperbolic sine function as the only nonlinear term, is proposed, as a modification of a hyperjerk system proposed by Leutcho et al.

Constrained controllability of nonlinear systems [PDF]
Proceedings of the 2003 American Control Conference, 2003., 1995 AbstractIn this paper infinite-dimensional dynamical systems described by nonlinear abstract differential equations are considered. Using the generalized open mapping theorem sufficient conditions for constrained exact local controllability are formulated and proved.

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.

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.

Nonlinear effect on quantum control for two-level systems [PDF]
J. Phys. B 42 (2009) 215504., 2009 The traditional quantum control theory focuses on linear quantum system. Here we show the effect of nonlinearity on quantum control of a two-level system, we find that the nonlinearity can change the controllability of quantum system. Furthermore, we demonstrate that the Lyapunov control can be used to overcome this uncontrollability induced by the ...

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 ...
