Abstract
An actuation system including a plurality of actuators; a plurality of position sensors coupled to the actuators, the plurality of position sensors providing rate feedback signals proportional to an actuator rate; a plurality of force sensors coupled to the actuators, the plurality of force sensors providing delta pressure signals; and a feedback control loop configured to receive the rate feedback signals and delta pressure signals and compute a difference in actual actuator rates and sum the difference with a computed difference in actuator forces to generate actuator positioning commands that equalize the actuator forces on a control surface.
Claims11
An actuation system comprising:
- a plurality of actuators;
- a plurality of position sensors coupled to the actuators, the plurality of position sensors providing rate feedback signals proportional to an actuator rate;
- a plurality of force sensors coupled to the actuators, the plurality of force sensors providing delta pressure signals;
- a feedback controller configured to receive the rate feedback signals and delta pressure signals and compute a difference in actual actuator rates and sum the difference with a computed difference in actuator forces to generate actuator positioning commands that equalize the actuator forces on a control surface;
- and
- a multiplication module, wherein a first force fight component is multiplied by a lead-lag factor to generate a factored first force fight component, the lead-lag factor being substantially equal to Kest/Aest and wherein the lead-lag factor accounts for an estimated force fight loop stiffness and for corrective gain factors.
