Analysis of a three-order autonomous chaotic circuit

A third-autonomous chaotic circuit is studied in this paper.The mathematic model is built,the chaos motion of the circuit is studied,and the chaotic motion of circuit is controlled with a method as controlling of bifurcation.The bifurcation diagram is plotted for the controlled system with parameter.The range of parameter to stabilize a certain nP periodic orbit in circuit can be obtained through the bifurcation diagram.The periodic orbit such as 1p,2 p can be stabilized with parameter..In addition,only by inputting single state variables of the system to one of subsystem,we can successfully control the chaotic motion of the circuit.It is easy to realize in circuit.
