This paper demonstrates how to design an H based damping controller for a HVDC link to enhance system damping under different operating conditions. Numerator-denominator perturbation representation is used to represent the model uncertainty and partial pole placement technique is employed to assign the critical mode to a specified location. A robust H controller is successfully designed by treating the change of operating conditions of the highly non-linear power system as model uncertainty. Simulation results show that the proposed controller is very effective to enhance the performance and robustness of the power system under the predefined uncertainties.
