Pitch feedback control splitting for helicopters with redundant actuators

摘要

Embodiments are directed to generating, by a processing device, a feedback command for an aircraft based on a reference input and an output response of the aircraft, and analyzing, by the processing device, the feedback command to allocate control to a plurality of control surfaces over a plurality of separate frequency bands.

主权项

1. A method comprising:
generating, by a processing device, a feedback command for an aircraft based on a difference between a reference input and an actual output response of the aircraft; analyzing, by the processing device, the feedback command to allocate control to a plurality of control surfaces over a plurality of separate frequency bands; applying an equivalence filter to the control that converts control of a first of the plurality of control surfaces into an equivalent amount of control in a second of the plurality of control surfaces to enable allocation over dynamically equivalent control surfaces; and applying an inversion of the equivalence filter to re-allocate control in an opposite or second direction.
