| Abstract: | Based on the principle of the decomposition method, the inverse operator expression of the periodic solutions for some nonlinear dynamic systems is given. The automatic calculation of this arithmetic is realized via computer program in Mathematica language. The examples of practical calculation are also presented and the calculation results obtained by this method are compared with those of the Runge-Kutta method. The calculation results show that this approach has the advantages of high accuracy and wide application, so it is an effective tool to calculate some type of nonlinear dynamic circuits. |
