Abstract :
In this paper, a Wien-bridge based circuit generating chaotic oscillations is designed and investigated both numerically and experimentally. The oscillator is extremely simple. It contains only a modified Wien-bridge oscillator and an additional hysteresis comparator. The typical waveforms and the phase portrait of the attractor are presented to illustrate the single scroll in a quasi-two-dimensional oscillator. This work should be a good supplement to the hysteresis chaos generating method. (ICCCAS´05).
