摘要
As for a large number of unknown frequencies of harmonic signals existing in the practice, the paper presents the detecting method utilizing the nonlinear chaotic dynamic system. Firstly, the method verifies being the periodic solution originated from the nonlinear equation theory, then founds the simulating model to calculate harmonic frequency using directional crossover technique. The technique is feasible through analyzing the absolute error and relative error of calculating results. At the same time, the paper brings forward the possibility to further detecting harmonic amplitude after detecting frequency.
