By introducing a flux‐controlled memristor with quadratic nonlinearity into a 4D hyperchaotic
system as a feedback term, a novel 5D hyperchaotic four‐wing memristive system (HFWMS) …

Research into metasurfaces is developing rapidly and is topical due to their importance and
applications in various fields such as communications, cryptography, and sensing, to name …

Despite having many similar characteristics with cryptography, existing chaotic systems
have many security issues that negatively affect the chaos-based cryptographic algorithms …

In this article, we focus on the state estimation problems for a system with protecting user
privacy. Regarding whether the user has conducted a sensitive action in the system as a …

In this paper, a hybrid control approach combining adaptive backstepping and fuzzy sliding
mode control is proposed for the synchronization of two Rossler chaotic systems. The …

In this paper, a fixed-time terminal synergetic observer for synchronization of fractional-order
nonlinear chaotic systems is proposed. First, fixed-time terminal attractors for fractional-order …

This paper presents a nonlinear equivalent-input-disturbance (NEID) approach to rejecting
an unknown exogenous disturbance in a nonlinear system. An NEID compensator has two …

In this work, we utilize two cascade coupling modes (unidirectional coupling and
bidirectional coupling) to construct a four-layer deep reservoir computing (RC) system based …

In this article, a simple yet efficient adaptive control method is proposed to investigate
synchronizing two chaotic systems. This approach presents an improved type-2 fuzzy …
