In this paper we consider the problem of optimizing the Frobenious norm of linear static feedback gains of a system with control structure and stability region constraints. We consider four important control structure constraints: 1) static output feedback; 2) constant gain feedback for multiple operating conditions; 3) two-controller feedback; and 4) decentralized feedback. We obtain a nonlinear programming formulation for the optimization problem and present an effective numerical approach for solving it. We include four examples.
