In this paper an adaptive deconvolution filter designthat takes into account small uncertainties in the system ispresented. An orthogonal basis is used for the realization of thefilter. The basis parameters are fixed and assigned robustly tooptimally deal with the system uncertainties. Finally, toincrease the capacity of the filter to track larger changes in thesystem dynamics, the adaptation of the coefficients thatlinearly combine the basis elements is considered. Performancecomparisons are included.
