A phase solution method of sinusoidal vibration signal based on second order generalized integrator
摘要
Abstract
To solve the phase difference problem of sinusoidal vibration signals,this paper utilizes the advantage of second order generalized integration for accurate signal tracking to solve the phase of sin-gle and the phase difference of dual sinusoidal signals.Firstly,taking a rotating machine as an exam-ple,the phase problem of sinusoidal vibration signals was analyzed.Then,combining the definition of second order generalized integrator frequency locked loop with prefilter and phase,a method for sol-ving the phase of sinusoidal vibration signals was designed.Finally,a numerical example was used to simulate the phase of single and the phase difference of dual signals,which verifies the accuracy of the phase solution method in this paper.关键词
