Frequency detection of self-adaption control based on chaotic theory*

Xu Yanchun; Qu Xiaodong; Li Zhenxing

Low-order Duffing and high-order Rossler chaotic oscillator are connected together and new self-adaption frequency detection method is presented. The frequency difference control between unknown signal and the periodic driving force is realized in this paper and the self-adaption is obtained. Thus, the detection precision and speed are promoted. The limitation that there are too many chaotic oscillators in Duffing system is broken. Meanwhile the disadvantage that the detection speed is lower in Rossler chaotic control is overcome. The self-adaption choice of frequency difference control is realized using the Duffing and Rossler different chaotic oscillators to obtain unknown signal frequency. The simulation results show that the presented method is feasible and effective.
