Abstract
An approximation procedure for the identification of a nonlinear bound ary heat transfer function in a one phase Stefan problem is presented. Alternatively the problem can be viewed as constructing a feedback co ntrol law for the control of the solidification surface in the Stefan problem. The analysis is based on Hilbert space methods and convex ana lysis techniques. Numerical results combining two regularization metho ds are presented.
