The design problem is split into a convex subproblem which can be solved efficiently by a Ricatti solver, and a non-convex subproblem which is solved using GA. For a 35th order model of the HVDC link considered here a first order controller that achieves robustness over a wide range of operating conditions is designed by imposing a H norm constraint. An additional pole region constraint is used to trade nominal performance against robustness.en1474-6670200411677681ElsevierAlgebraic Ricatti equationDecentralized controlFixed structure controllerGenetic algorithmsRobust controlTechnikIngenieurwissenschaftenConference Paper10.1016/S1474-6670(17)31687-7Other
