Recherche et étude de la stabilité du cycle limite pour l'oscillateur de Rayleigh

In this paper, we studied Rayleigh autonomous oscillator by searching its limit cycle and by studying the stability of the cycle. Through this study, we studied the fixed points of the equation of Rayleigh oscillator and we realized that in reality this oscillator has only one fixed point. What appears new according to our point of view is that we found the cycle limit of the oscillator using a form of Poincaré-Bendixson theorem. Then, we studied the stability of this limit cycle by the method of multiple scales. Finally, the most important is that in this paper we have shown analytically and confirmed by numerical simulation using Mathematica that the Rayleigh oscillator exhibits a bifurcation of PAH
