摘要
本文用 Melnikov 方法研究了调频输入正弦合成锁相环路方程的次谐波解的存在性与浑沌(chaos)性质,讨论了分枝到 smale 马蹄的途径,给出了分枝到多重横截同(异)宿环型浑浊的条件,最后证明了 Birkhoff 吸引集合的存在性。
In this paper,by using Melnikov Method,We investigate the existence of subharmonic solutions and chaotic behaviour in the equation of phase-locked loops.We study the routes of horsehoes are created in parameter space.Various conditions of bifurcation to chaos can be obtained and the existence of Birkhoff attracting set can be proved.
