Abstract [en]

Modelling the whole power system of an airborne system requires very high computational capacity. This paper presents a possible approach to overcome this obstacle when considering new technology and topologies in airborne systems. Using controlled current converters and electromechanical actuators for rudder control are examples of such new technology. The governing idea is to separate the high (electrical) and low (mechanical) frequency parts [1] of the model and thereafter only consider the low frequency part. Electrical components as current and/or voltage converters/inverters are then desccribed in terms of efficiencies or in circuit diagrams in form of load dependent resistors [2] and in electromachines by means of load dependent loss resistances equivalent with their electromechanical efficiencies [3]. Step-down and step-up voltage converters are desccribed as fictive DC/DC transformers. This approach makes it possible to reduce the complexity of power system models of tentative systems to such extent that the resulting computational tool can be used for studies of the system performance during entire flight missions and/or for optimisation.
