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.
