对一个新超混沌电路的研究

本文提出一种新的产生超混沌的电路。该电路非线性器件的选取不同于以往只局限于分段线性电阻的框框，而是采用分段线性负电容作为非线性元件。

Study On a Novel Hyperchaotic Circuit

This paper proposes a novel circuit which generates hyperchaos.Choice for nonlinear elements in the circuit differs from that of the conventional circuit which considers only piece-wise linear resistors.It utilizes piece-wise linear negative capacitance as the nonlinear element.The complex nonlinear dynamical nature of this circuit is analyzed by computer simulation and circuit experiment and hyperchaos,sub-hyperchaos,chaos,quasiperiod and period oscillations have been found simultaneously.The non-negative Lyapunov exponents were directly calculated from the time series of state variables obtained in circuit experiment by initially using what we call the attractor reconstructing technique.
