Abstract: Chua’s circuit can produce complex nonlinear dynamics,the state of which is three order differential equations and which is used to study chaos behavior.Firstly,a voltage driven model of Chua’s deformed circuit is set up.Secondly,an analytical method to predict the scope of the parameters of chaos of the third-order nonlinear differential equations is proposed.At last,numberical method and Lyapunov exponent analysis are used to simulate the prediction result,which verifies the correctness of chaotic prediction analysis of this circuit.

Key words: voltage driven;Chua&rsquo, s circuit;chaos;analytical prediction
