Abstract :
In this paper a system of paralleled DC/DC converters operating in CICM with CMC is modelled and analysed. The H∞ control design is used in order to guarantee the robust stability and robust performance of the system in spite of different uncertainties. The μ-analysis is used to evaluate the robustness of the system. Simulation results are presented to demonstrate the control design procedure.
