We want to estimate a very non-linear function, i.e., the hysteresis effect of friction in robots and machine tools. What are the most appropriate tools to do this estimation? We were looking in the direction of Bayesian methods, because we have quite extensive models of the hysteresis curve. The problems we have are that the nonlinearities are of two difficult origins: (i) multiple valued, and (ii) with non-smooth ``switching'' behavior... More details about the problem and the model are to be found in a PDF file at <http://www.mech.kuleuven.ac.be/~bruyninc/hyster.pdf> Thanks for any hints :-) PS BTW where are the archives of this mailinglist? -- [EMAIL PROTECTED] (Ph.D.) Fax: +32-(0)16-32 29 87 Dept.
