Abstract:

First,the dynamic characteristics of the circuit system under the influence of various circuit parameters are analyzed on the basis of the periodic orbit theory about the chaotic attractor and by means of the circuit simula-tion technology,and the chaotic region diagram in the circuit parameter plane is presented.Next,the standard values of circuit parameters and the maximum possible parametric range when the circuit has 2-scroll attractors are calculated according to the presented chaotic region diagram.Finally,the steps of the algorithm in selecting the pa’rameters of the Chuag circuit are proposed.All these provide theoretical guidance for the realization of the chaotic oscillatory circuit.

Key words: Chua’s chaotic circuit, tolerance analysis, Chaos attractor, circuitry realization
