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 ...

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

Sliding control of MIMO nonlinear systems [PDF]
Modeling, Identification and Control, 1991 Sliding control of MIMO (multivariable input multivariable output) nonlinear minimum phase systems is discussed. Stability conditions related to model errors are emphasized.

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.

Accessibility of Nonlinear Time-Delay Systems [PDF]
, 2017 A full characterization of accessibility is provided for nonlinear time-delay systems. It generalizes the rank condition which is known for weak controllability of linear time-delay systems, as well as the celebrated geometric approach for delay-free ...

Constrained controllability of nonlinear systems [PDF]
Proceedings of the 2003 American Control Conference, 2003., 1995 This paper contains constrained exact local controllability results for nonlinear abstract differential equations. A generalization of the open mapping theorem is used for the sufficient conditions to guarantee controllability. The values of controls are in a convex, closed cone with vertex at 0.

Unconstrained receding-horizon control of nonlinear systems [PDF]
, 2001 It is well known that unconstrained infinite-horizon optimal control may be used to construct a stabilizing controller for a nonlinear system. We show that similar stabilization results may be achieved using unconstrained finite horizon optimal control ...

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.

On a switching control scheme for nonlinear systems with ill-defined relative degree [PDF]
, 2002 This paper discusses the applicability of a switching control scheme for a nonlinear system with ill-defined relative degree. The control scheme switches between exact and approximate input-output linearisation control laws.
