Study on eigenvalue space of hyperchaotic canonical four-dimensional Chua's circuit

The eigenvalue space of the canonical four-dimensional Chuas circuit which can realize every eigenvalue for four-dimensional system is studied in this paper. First, the analytical relations between the circuit parameters and the eigenvalues of the system are established, and therefore all the circuit parameters can be determined explicitly by any given set of eigenvalues. Then, the eigenvalue space of the circuit is investigated in two cases by the nonlinear elements used. According to the types of the eigenvalues, some novel hyperchaotic attractors are presented. Further, the dynamic behaviours of the circuit are studied by the bifurcation diagrams and the Lyapunov spectra of the eigenvalues.

Design of Remote Virtual Experiment Based on MATLAB and .NET

This paper presents a framework for remote virtual experiment implementation. The work principle of the solution is described and the three-tier structure of the system is proposed. The proposed solution is based on two commercially available software packages. MATLAB/SIMULINK is used for experiment module development, while.NET is used for the user front-end interface. The virtual experiment is divided into two kinds, static one and dynamitic one. The static remote virtual experiment is designed by MCR interface and the dynamitic one is done by MATLAB engine technique. In addition, two samples of remote virtual experiment are deployed to user.
