Formulas for the amplitude of the van der Pol limit cycle through the homotopy analysis method

López García, José Luis ; Abbasbandy, S.; López Ruiz, R. (Hindawi / Wiley, 2009) Artículo / Artikulua

The limit cycle of the van der Pol oscillator, x¨+ε(x2−1)x˙+x=0, is studied in the plane (x,x˙) by applying the homotopy analysis method. A recursive set of formulas that approximate the amplitude and form of this limit ...
