Adaptive frequency detection method based on frequency difference control

Abstract

In this paper, an adaptive frequency detection method based on frequency difference control is proposed. By controlling the frequency difference between the frequency of the signal to be checked and the frequency of the periodic policy, the adaptive selection between two kinds of chaotic vibrators is realized, thus the detection speed is accelerated, the detection accuracy is high, and the error is small. At the same time, the stability of adaptive frequency detection method based on frequency difference control is analyzed, and the simulation results show that the detection method has good stability.
