For a three-dimensional autonomous four-wing chaotic attractor, this paper rigorously
verifies its chaotic properties by using topological horseshoe theory and numerical …

The design of adaptive chattering‐free sliding mode controller (SMC) for chaotic systems
with unknown input nonlinearities is studied in this paper. A smooth hyperbolic tangent …

The crash of an aircraft with an almost vertical attitude in Wuzhou, Guangxi, China, on 21
March 2022, has caused a robust discussion in the civil aviation community. We propose an …

In this paper, first, a nonlinear feedback controller for achieving chaos control of a novel
multi-wing chaotic system is presented. The nonlinear feedback controller has two parts. The …

This paper addresses the problem of coexistence of synchronization and anti-
synchronization (CSAS) for a class of switched chaotic systems by adaptive control method …

This paper addresses the problem of projective synchronization of chaotic systems and
switched chaotic systems by adaptive control methods. First, a necessary and sufficient …

Zhang-gradient (ZG) method is a combination of Zhang dynamics (ZD) and gradient
dynamics (GD) methods which are two powerful methods for online time-varying problems …

Controlling nonlinear systems with linear feedback control methods can lead to chaotic
behaviors. Order increase in system dynamics due to integral control and control parameter …

In last decades, chaos phenomenon and chaotic systems are defined as a nonlinear
behavior have received a plenty of attention. In many areas, a chaotic system is used due to …

In this paper, synchronization of identical switched chaotic systems is explored based on
Lyapunov theory of guaranteed stability. Concepts from robust control principles and …
