Experimental and numerical determination of phase synchronization between a Chua system and an external periodic signal

Experimental and numerical determination of phase synchronization between a Chua system and an external periodic signal

We present our first experimental results in relation to the phase synchronization of a single sinusoidal function to a Chua oscillator. We approached the synchronization process with real time observation. We were able to observe that a Chua oscillator will stay phase synchronized if the periodic signal has the appropriate amplitude and frequency, i.e., falls inside a synchronization tongue (Arnold Tongue). These early results will be compared in the future with numerical simulations.
