Software Emulation And Circuit Realization Of Chaos Control To Rossler Dynamics System

The third order nonlinear autonomous electronic circuit based on Rossler equation is build。Furthermore , the suitable circuit parameter is selected to carry on Multisim circuit emulation and electronic circuit experiment . As the parameter of Rossler system is changing, the bifurcate process form the steady periodic state to chaotic state is observed by using oscillograph. We study time series in chaotic state by the means of computing maximal Lyapunov exponent, correlation dimentions, approximate entropy.The system is effectively controlled via nonlinearly feedback control or feedback control . As the value of feedback gain is changing, the system can from chaotic state to the periodic state.
