In this paper an iterative technique based on the successive centering method is proposed for designing a robust decentralized low-order controller for a High Voltage DC power transmission link. Starting with an arbitrary stabilizing low-order controller obtained via dual iteration, in a three-stage procedure this controller is successively (i) transformed into a decentralized structure, (ii) made robust against admissible parameter variations by imposing a H norm constraint, and (iii) tuned for a fast response by pushing closed-loop poles to the left. Simulation results illustrate the achieved robust performance of the HVDC power link under different operating conditions.
