This paper proposes design of optimal and robust coordinated controller of hybrid energy storage system in a naval DC microgrid (MG) application. It is able to mitigate the negative effects of the pulsed power loads and meet the practical limitations of both converters input control and state variables signals based on IEEE standards. To do this, first, the dynamic model of the DC MG, which can represent in either all-electric aircraft or shipboard power systems is developed. Second, a novel model predictive controller (MPC) for energy storage converters is proposed such that all of the mentioned hard constraints are guaranteed. Third, a linear matrix inequality (LMI) approach is used to solve the MPC conditions. Finally, to evaluate the applicability and effectiveness of the proposed approach, some experimental tests are extracted. Obtained results verify better performance of the proposed approach over other state of the art control techniques.

a new configuration of three-Ievel z-source inverter has been proposed. The proposed inverter is based on nine-switch configuration reduces the number of switches compared to other configurations while retaining their attractive capabilities such as voltage boosting and low harmonic content. The detailed switching implementation method is analyzed and the suitable periods for applying shoot-through states are presented. To validate the proposed inverter, simulations have been performed using MATLAB/SIMULlNK and the results are provided.
