A generic method for robust performance analysis of aircraft DC power systems

The recent evolution of aircraft power networks makes new design study necessary for solving key issues such as optimal efficiency, reliability, adaptability and performances. Indeed, DC power systems are subject to strong dynamic interactions between the source and the loads. In this paper, the need for a new design method of the power network is explained, and the authors propose to use a robust performance analysis method. The first main result concerns the analysis of the robustness of a classical aircraft DC source where the parameters of the DC bus are unknown. The second one shows the efficiency of the method to evaluate the potential gain in weight from a change in the performance specifications at the system level.
