One continuous and digital chaotic attractor

摘要

Implementation of continuous chaotic systems in not easy task, because of strong sensitivity on parts parameters values, e.g. temperature dependence etc. On the other hand the digital systems can be easily simulated and inexpensive constructed with almost the same behavior as continuous systems. Digital chaotic attractor also enables simply changing parameters of system. This paper describes a new four-dimensional digital autonomous chaotic system derived from continuous chaotic system. Analysis of the results shows that this system has complex dynamics with some interesting characteristics. The digital chaotic system was also realized by means of microcontroller.
