Abstract
Previous experimental results on the feedback stabilization of a "drift-type" instability are interpreted in terms of a nonlinear theory of the Van der Pol type. This theory predicts a variation of the instability amplitude and its frequency as a function of the gain and the phase angle in the feedback loop. Comparison between these predictions and the experimental results shows remarkably good agreement.Keywords
