Active Control System of Parallel On-Line Modeling Algorithm Based on Error Path
Tianming Zhao · Measurement & Control Technology · 2010
An ANC(active noise cancellation) system with a new parallel on-line modeling algorithm is presented.This new algorithm uses three adaptive filters.Furthermore,a new delay element is used to guarantee an unique solution to these adaptive filters.Mathemtical analysis of the algorithm and simulation show that unbiased estimation of the error path can be achieved.
