Description
When the ANC system is operated on the Filtered-x LMS algorithm, the step size parameter for stable control has been decided by trial and error, because the way of obtaining it has been unknown up to this time. In this paper, we derive an equation of obtaining the value of the step size parameter that shows the stable limit of the system, from the allowable phase difference between C and C^^⋀, when C^^⋀ is the model of Error Path C, and includes modeling error. Next, we try to express the equation as a function of the information obtained from estimating C. In addition, we show the effectiveness of the proposed equation from the comparison of the convergence property of the case using the step size parameter from the equation with that of the other case.
