The 380 still has the original 3 hyd systems green, yellow, blue, which the computers will control in these configs therefore on aileron for each hyd system.
The A380’s flight controls are hydraulically powered as always. But there are only 2 hydraulic systems instead of 3. There are no more the Blue system. The Green and Yellow systems are powered by engine-driven pumps and operate at 5,000psi instead of the 3000psi the Green, Blue, Yellow system used in other aircraft in the Airbus family to reduce weight.
2 actuators move each of the 3 ailerons in a wing. The inboard and middle ailerons are moved by a hydraulic actuator and an electrohydrostatic actuator EHA but the outer aileron is moved by 2 hydraulic actuators.
The electrical backup hydraulic actuators EBHAs has replaced the Blue hydraulic system. It is these EBHAs (it combines hydraulic servocontrol and EHA functions in a single unit) that help operate and move the inboard and middle ailerons in an event of dual hydraulic loss so handling performance is not compromised. At high speeds the outer ailerons are locked out anyway in rolls.
