چکیده :

In a hybrid photovoltaic-battery system, the battery connects to photovoltaic renewable resource via a bidirectional DC-DC converter. Among the existing bidirectional converters, the half-bridge topology has been selected here, due to some advantages, as high efficiency and low size inductor. This study presents an -based robust control for the non-isolated bidirectional half-bridge converter, by solving a mixed sensitivity problem, in a hybrid photovoltaic-battery system. The main advantage of the proposed technique is the ability to tackle a wide range of external disturbances and model uncertainties. The presented algorithm is simulated in Matlab/Simulink and evaluated under voltage and load changes. The numerical results show that the controller has the ability to maintain the half-bridge converter performance, under different perturbations.
