N2 - A consistent framework for robust linear quadratic regulators (LQRs) control of Dual-Active-Bridge Isolated-Bidirectional DC-DC (DAB-IBDC) converters is presented. The conventional LQR controllers are effective with respect to a certain performance index and have a good performance in stability. However, it cannot assure robust stability with high uncertainty. In this paper, after obtaining a convex model of DAB converter's dynamics that covers the uncertainty of parameters, the linear matrix inequalities (LMIs) are proposed to optimize the performance. Then, a new robust control method called LMI-LQR control for DAB converters is derived. The performance comparison with the conventional LQR is conducted. Finally, the performances of stability and dynamic respond are discussed for load perturbations of DAB converters.
