Abstract :
In this paper, we are concerned with the online identification of two different coefficients for a one-dimensional heat equation, among which one parameter is in the spacial domain and the other appears in the boundary. We prove that the coefficients are identifiable when the plant is excited by a nonzero constant boundary input, and adaptive identifiers are constructed to estimate these unknown parameters.
