1. A method for predicting limit cycle oscillations, the method comprising the steps of:

  • generating a signal based on oscillatory behavior;

    statistically processing the signal to obtain a generalized Teager measure;

    monitoring instantaneous changes in the generalized Teager measure; and

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