This paper considers controller design for power electronic converters, which are used in hybrid energy systems. Due to the number of variables to be controlled and presence of disturbances and uncertainties, a robust decentralized controller is presented. In this regard, first, a state-space model of the two-input SEPIC, which is a buck-boost converter and conducts in continuous conduction mode, is derived. Then parametric uncertainty in the state-space matrices is represented by input perturbation, in terms of ∆-M representation. Next, the parameters of a robust decentralized PI controller are designed using μ-synthesis. Simulation results are used to verify the performance of the proposed controller.
