Scheme analysis of power-by-wire airborne actuation systems

Some existing power-by-wire (PBW) airborne actuation systems, such as integrated actuation package, electro-mechanical actuator and electro-hydrostatic actuator, were summarized. The two kinds of the new PBW actuation system, i.e. the electromotor-pump compound control and the electromotor-pump-valve compound control, were proposed. The preliminary experimental analysis have demonstrated that the two new kinds of PBW actuation system, as transition toward all-electric actuation systems, are feasible.
