This paper deals with the modeling and control of an electrical source for the future “All Electric” aircraft. It is constituted by a rotor wounded synchronous generator and a diode rectifier feeding the DC power system. Using H∞ control theory, this paper shows that usual disturbance rejection standards can not be met with such an electrical power source and new standards should be defined. Simulations...
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...
A new methodology for aircraft HVDC power systems design is first proposed. The first goal is to design the network subsystems in order to obtain optimal devices from a weight point of view. The contribution of optimal linear multivariable control methods is shown to be major for this first design objective and Hinfin synthesis is applied in this paper. The second design objective is that the devices...

Improving the braking energy recovery efficiency in light rail systems can reduce their energy consumption. In order to compare and quantify contribution of different technologies with respect to traditional light rail systems, a quasi-static decoupled load flow modelling of a power supply network with AC-DC converters has been developed by the authors. It uses an empiric model of uncontrolled rectifiers...
