Lyapunov-Based Stability Analysis of Adaptive Neural-Network Controllers for Nonlinear Perturbed Systems

A Lyapunov-based framework for stability analysis and synthesis of adaptive neural-network (NN) controllers for a class of uncertain second-order nonlinear systems (SNS) with bounded external perturbations and unmodelled dynamics is presented. Online learning is employed for the reconstruction of the plant nonlinearity...

Investigating Chaos and Exact Solutions in Electromagnetic Wave Dynamics Governed by the Time-Fractional Drinfel’d–Sokolov–Wilson Equation

Nonlinear electromagnetic wave propagation in complex plasma environments has attracted considerable attention due to its important applications in nonlinear optics, plasma physics, space science, and communication technologies. In the present study, a time-fractional Drinfel’d–Sokolov–Wilson equation (DSWE) is investi...
