Time varying Eigensystem Realization Algorithm with repeated experiments Conference Paper uri icon


  • This manuscript presents an extension of the celebrated Eigensystem Realization Algorithm (ERA)to include the identification of time varying systems. Time varying system models, in discrete time are introduced and the differences and unique properties are discussed in the light of the time invariant system models. Realization theory specialized to account for the time variation of the system models is revised to setup the conventions for the remainder of the paper. This is followed by a brief presentation of the Eigensystem Realization Algorithm for the linear time invariant plant models. The generalization of this algorithm is presented and is discussed with an example.
