A robust control design process based on a linear Matrix Inequalities (LMI) for a Single Inductor Multi Output (SIMO) boost converter has been presented in this paper. Considering complicated multi-stages operation of SIDO converter, Signal Flow Graph (SFG) modelling was used to predict all behavior of the converter. Using the SFG model, nonlinearities and uncertainties was modelled as a convex polytope for LMI design constraints. This method guarantees a certain perturbation rejection level and a region of pole location. The derived parameters from LMI were applied on state-feedback coefficients in Matlab/Simulink to show the validity of the presented LMI method. Finally, the obtained results have been compared with a conventional PI controller.

In the present paper the structure of a single inductor double output converter (SIDO) has been studied. One of the major challenge, to design a controller in SIDO Converters, is removing the cross-regulation among the outputs. On the other hand, the multi-stages operation of SIDO converters cause, to achieve the model which predicts their all behaviors, be more difficult than typical converters. In this paper a SIDO Boost/Boost converter is modeled by a systematic signal flow graph (SFG) modelling. Based on obtained model a multivariable control scheme has been proposed to reduce the cross regulation of the output. Finally Simulation results are included to show the validity of the obtained model and the designed Controller.
