On-line robust parameter identification for parabolic systems

In this paper a robust scheme for the adaptive parameter identification of parabolic distributed parameter systems is developed. Results from the finite-dimensional treatment of the parameter projection method and sigma (sigma) modifications to the standard adaptation rules are extended to infinite-dimensional systems. For the class of systems under study, modifications to these standard parameter adaptation rules were deemed necessary in order to account for the additional mathematical subtleties that arise when dealing with infinite-dimensional systems.
