Solak, E.Morgül, O.Ersoy, U.2016-02-082016-02-0820010375-9601http://hdl.handle.net/11693/24899We consider the control of a class of chaotic systems, which covers the forced chaotic oscillators. We focus on two control problems. The first one is to change the dynamics of the system to a new one which exhibits a desired behavior, and the second one is the tracking problem, i.e., to force the solutions of the chaotic system to track a given trajectory. To solve these problems we use observers which could be used to estimate the unknown states of the system to be controlled. We apply the proposed method to the control of Duffing equation and the Van der Pol oscillator and present some simulation results. © 2001 Elsevier Science B.V.EnglishChaos synchronizationChaotic systemsFeedback systemsStabilizationState observersTrackingChaotic dynamicsControl systemFeedback systemMathematical analysisOscillatorSimulationArticle10.1016/S0375-9601(00)00808-2
