The use of a constrained equation is one of most powerful approaches in the
analysis of chaos. In a previous paper we studied, in detail, chaos in a f
orced Rayleigh oscillator with a diode, by regarding the diode as a switch.
The Poincare map was derived as a one-dimensional (l-D) mapping and, by th
is mapping, the generation of chaos was explained. In this paper, Re study
chaos synchronization of a pair of forced Rayleigh oscillators with diodes.
By regarding the diodes as switches, chaos synchronization is accomplished
very easily, without using a wide frequency band, and is realized in circu
it experiments.
