| Abstract |
Subsystem interaction in a simplified power distribution system of a next generation transport aircraft is addressed. Detailed analysis of interaction between an ElectroMechanical Actuator (EMA) connected to the DC bus of the power distribution system in a next generation transport aircraft with the bus regulator is presented. The classical impedance ration criterion is used to determine local stability arround an equilibrum point of each interface by observing the impedance characteristics of the source and load subsystems. Critical parameters that determine the local stability of the integrated system are identified. The loss of stability under large disturbances is presented to motivate the use of nonlinear stability analysis methods. Preliminary results of nonlinear stability analysis are presented. |
