Retrieval of unknown sinusoidal signals through the measurement of chaotic signals

Abstract

Chaotic dynamical systems are extremely sensitive to initial conditions and their behaviour is unpredictable. On the other hand, in regulation theory, an exosystem is available when it is known; however, if it is unknown, it should be estimated with any adaptable recognition technique. This Letter presents a perturbed chaotic oscillator by an unknown sinusoidal signal, in which the perturbed signal is estimated by measuring the output of the chaotic oscillator.
