β¦ Synopsis
The elliptic perturbation method is applied to the study of the periodic solutions of strongly quadratic non-linear oscillators of the form xΒ¨+ c1 x + c2 x 2 = ef(x, xΛ), in which the Jacobian elliptic functions are employed. The generalized Van der Pol equation with f(x, xΛ) = m0 + m1 x -m2 x 2 is studied in detail. Comparisons are made with the solutions obtained by using the Lindstedt-PoincareΒ΄method and Runge-Kutta method to show the efficiency of the present method.

An elliptic perturbation method is presented for calculating periodic solutions of strongly non-linear oscillators of the form xΒ¨+ c1x + c3x 3 = ef(x, xΛ), in which the Jacobian elliptic functions are employed instead of usual circular functions in the conventional perturbation procedure.

The multiple scales method, developed for the systems with small non-linearities, is extended to the case of strongly non-linear self-excited systems. Two types of nonlinearities are considered: quadratic and cubic. The solutions are expressed in terms of Jacobian elliptic functions. Higher order ap
The new idea of calculation of limit cycles of strongly non-linear systems and its several numerical examples were presented in [1]. It is interesting to study the calculation of limit cycles of non-linear systems further, however some defects have been found in [1].
The semi-stable limit cycle and bifurcation of strongly non-linear oscillators of the form xK #g(x)" f (x, xR , )xR is studied by the perturbation-incremental method. Firstly, the ordinary di!erential equation is transformed into an integral equation by a non-linear time transformation, then the ini
