In this paper, we propose new LMI-based conditions to design output-feedback controllers under structural constraints. The conditions are represented in terms of LMIs with rank constraints and we apply the alternating projection method to solve them. Even though the alternating projection algorithm does not ensure global convergence, extensive numerical experiments demonstrate that the proposed design method is promising in designing structured controllers. The difficulties and limitations linked with the proposed design method is also discussed.
