In this paper an approach to designing controller for a VSC HVDC terminal which is robust over a range of operating points is presented. The operating range of the terminal is first characterized as an uncertainty region around a linear nominal model using the operating points of a non-linear model. Linear fractional transformation (LFT) uncertainty model is constructed using a technique based on the singular value decomposition. An LMI based formulation is then used to synthesize controller which optimizes the performance over a range of operating conditions. Numerical simulation confirms that the designed controller achieves good trade-off between the robustness and performance on the non-linear model.
