Controlling variable wind speed turbine (VWT) system based on a doubly-fed induction generator (DFIG) is a challenging task. It requires a control law that is both adaptable and robust enough to handle the complex dynamics of the closed control loop

The problem of passivity-based sliding mode control is considered, for the unified chaotic system having uncertainties and perturbations. Using a combination between sliding mode method and the passivity method, an appropriate switching surface for t

This article considers the passivity control of chaotic systems under the presence of uncertainties and perturbations. Passivity-based controllers are applied that can achieve stabilization at any equilibrium point of the system, or synchronization.

In this paper, a new encryption approach based on optical time-delay chaotic system and a wavelet is proposed for date transmission. The general principle of this method is to drown the image in the chaos before inserting it into the approximation of

This work proposes a novel hyperjerk system, as a generalization of a hyperjerk system proposed by Dalkiran and Sprott. Initially an analysis of the dynamical behavior of the system is performed. Then, the system is applied to the problem of secure c
