Title
A general active stabilizer for a multi-loads DC-power network
Abstract
In the More Electrical Aircraft (MEA) project, the many electric actuators situated in several part of the plane will impose to implement some complex DC-power network to ensure the energy transfer. In the MEA context, the design of the DC-networks should respect some constraints as size and weight which correspond to both practical and economical reasons. Heeding of these, optimization of the different passive elements like DC-bus capacitance and filtering inductance is a main issue. Unfortunately, it is known that the reduction of DC-bus capacitance may lead to instability of a HVDC network. In order to consider the instability risk in an application case, this paper will propose a centralized method to stabilize a multi-loads DC-network. The proposed method used the Lyapunov Theory to generate a global command law for a whole electric DC-network. A stabilizing feedback is designed which ensures that the nonlinear model of the system is solution of the Lyapunov Equation and a general way to design the stabilizing supervisor is presented. Its implementation is well adapted to DC-power network as it permits to generate a n size stabilizing signal vector for a system with n loads. With this supervisor, the global large signal stability of the system is achieved.
