In this paper one of approaches to parametric identification of plants with distributed parameters is considered. The approach is based on the exponential modulation method (EMM). This method, originally developed for objects with lumped parameters and described by rational transfer functions, is extended for identification of plants described by irrational transfer functions. As an example, the process of radiation heating of the solid is considered for various boundary conditions.
