A control system may be used to control actuators that actuate movement of flight control surfaces of an aircraft. Each actuator is couplable to a flight control surface and includes a motion control assembly having a hydraulic motor and a drive path from the hydraulic motor to the flight control surface. Each hydraulic motor includes an extend port and a retract port. The system includes a hydraulic control module fluidly connected to the extend port and the retract port of each hydraulic motor and a controller operable to output hydraulic power from the hydraulic control module to the motion control assembly to actuate movement of the flight control surfaces. The controller is configured to identify an actuator that positionally leads the other actuators and reduce hydraulic power to the motion control assembly assigned to such actuator.
A control system for controlling a plurality of actuators, the control system comprising:
A method for controlling a plurality of actuators for actuating movement of one or more adjustable components of an aircraft, the aircraft including a plurality of actuators for actuating movement of one or more adjustable components, wherein each actuator has a first end couplable to a structure of the aircraft and a second end couplable to one of the one or more adjustable components and each actuator additionally includes a motion control assembly having a hydraulic motor and a drive path from the hydraulic motor to the one or more adjustable components, wherein the one or more components is configured to move along a respective drive path, the method comprising:
