In this paper an iterative technique based on a combination of Riccati solver and Genetic Algorithm (GA) is applied to the problem of designing a decentralized robust low-order controller for a High Voltage DC power link. 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.
