A stack-based chaotic algorithm for encryption of colored images [PDF]
Journal of Artificial Intelligence and Data Mining, 2017 In this paper, a new method is presented for encryption of colored images. This method is based on using stack data structure and chaos which make the image encryption algorithm more efficient and robust. In the proposed algorithm, a series of data whose

Broken Symmetry in a Memristive Chaotic Oscillator
IEEE Access, 2020 A generalized memristor is introduced in Liu-Chen chaotic system for amplitude control. Different from other chaotic systems, the oscillation behavior can be rescaled in amplitude and frequency by three independent controllers. One controls the amplitude

THE ADAPTIVE CONTROL OF CHEN’S CHAOTIC SYSTEM
Acta Physica Sinica, 2001 The control of Chen's chaotic system when its parameters are known a priori or unknown is studied by means of a simple linear state feedback method. When the parameters are known a priori, we show the variation range of feedback gain; and when the parameters are unknown, an adaptive controller is designed, which overcomes the drawback that the control ...

Nonfeedback control of Chen’s chaotic system
Acta Physica Sinica, 2007 Nonfeedback chaos control of Chen's chaotic system is realized with nonresonant parametric drive. The control input is a periodic signal whose frequency is far higher than the system characteristic frequency. The feasibility of this scheme is proved by averaging method and Lyapunov method, and the condition of control parameter is obtained.

Fuzzy Sliding Mode Control for Hyper Chaotic Chen System
Advances in Electrical and Computer Engineering, 2012 In this paper, a fuzzy sliding mode control method is proposed for stabilizing hyper chaotic Chen system. The main objective of the control scheme is to stabilize unstable equilibrium point of the system by controlling the states of the system so that ...
