Identification of 2D Interconnected Systems: An efficient Steepest-Descent approach

In this paper, a new identification method for large 2D grids of interconnected systems is presented. The proposed algorithm minimizes the Output-Error of the lifted system by using a Steepest-Descent optimization method which exploit the Multilevel Sequentially-Semi Separable (MSSS) structure of the involved matrices. Furthermore, it is...
