title: Identifying system structure from controlled steady-state responses.
abstract: We suggest a control based method to uncover the structure (i.e., the dynamics of each system, the coupling direction, and coupling functions) of coupled systems. We show that driving a coupled system to steady states can reveal the underlying controlled coupling structure. An example of interacting quantum dots is presented to illustrate the structure identification method suggested.
