In order to study more exactly the chaotic system established by a particular Duffing Holmes equation for determining the unknown frequency of weak harmonics, the existence of periodic solutions for the equations is proved and the solution is unique. The periodic harmonic characteristics The experimental results show that the corresponding α values for different frequency bandwidths and frequencies need to be determined through careful simulation.
