Abstract:This paper presents a novel convergence analysis of the narrowband active noise/vibration system with FXLMS-based algorithm. It is revealed that the convergent behaviour mainly depends on the phase error of the secondary path model as well as the structure of the controller. With a constant step size, the convergent speed of the algorithm is maximized at a critical value of the phase error. The algorithm exhibits different convergent behaviours if the phase error is below or above this critical value, respecti… Show more
