1. A method for predicting limit cycle oscillations in a natural system, the method comprising the steps of:

  • measuring oscillatory behavior in the natural system to obtain a first signal based on the oscillatory behavior;

    statistically processing the first signal to obtain a corresponding envelope signal;

    monitoring instantaneous changes in a function which is based on the envelope signal; and

    generating a classifier signal when the instantaneous changes are less than a predetermined threshold value for a predetermined time period whereby the classifier signal is a prediction of the limit cycle oscillations.
