Summary:The LMS algorithm forms the core of a number of adaptive control
schemes. It has on one hand provided certain degree of robustness to
these algorithms but on the other hand its convergence rate is
notoriously slow. We propose a method to initialize the LMS algorithm
which dramatically shortens its adaptation period. We also prove that
under certain condition this initialization can be computed without
explicit knowledge of either the reference or noise spectrum. Although
the work is illustrated using the filtered-X scheme, this idea can also
be applied to other similar schemes. Two successful experiments starting
from black-box identification to real-time control have verified the
effectiveness of this idea
