Vibe is a Java-based simulator, but you now have Java turned off. You may turn on Java at any time.

Vibe:Relaxation Oscillators:Rayleigh Oscillator

The Rayleigh oscillator is much like the van Der Pol oscillator save one key difference: as voltage increases, the van Der Pol oscillator increases in frequency while the Rayleigh oscillator increases in amplitude.

Here is the second order differential equation for the Rayleigh oscillator:

Like the van Der Pol oscillator, Omega controls how much voltage is injected into the system. Alpha controls the way in which voltage flows through the system. See the writeup on the van Der Pol oscillator for more on how this works.

There seem to be many definitions of the Rayleigh oscillator. If anyone has a good definitive source on the right one, please send email to me at eckdoug[AT]iro[DOT]umontreal[DOT]ca
