Abstract: With the quickly development of virtual instrument technique, it provides a new approach for the research of nonlinear system. Three-dimensional multi-scroll chaotic system based on virtual instrument is designed. The experimental results of three-dimensional multi-scroll chaotic circuit system are presented. As the approach has been used, the result at the experimental system is satisfactory.

Key words: virtual instrument, LabVIEW, chaotic circuit, three-dimensional multi-scroll chaotic attractor
