Title: APPARATUS TO ESTIMATE THE ROOT MEANS SQUARE VALUE OR THE AMPLITUDE OF LIMIT CYCLE OSCILLATIONS IN SYSTEMS THAT ENCOUNTER OSCILLATORY INSTABILITIES AND METHODS THEREOF
Abstract:
Oscillatory instabilities are ubiquitous of systems, and these usually arise out of low amplitude aperiodic oscillations. These oscillatory instabilities generally affect the performance and the lifespan of systems in an adverse manner. An apparatus and a method are disclosed here to estimate the rms value or the amplitude of limit cycle oscillations for control of the oscillatory instability.
