The problem of periodic solutions of nonlinear autonomous systems with many degrees of freedom is considered. This is made possible by the development ora modified version of the KBM method. The method can be used to generate limit cycle phase portrait, amplitude, period and to indicate stability of the limit cycle. 相似文献
