A method of mitigating force-fighting in an actuation system comprising two or more actuators arranged to position a surface; the method comprising determining an offset between a desired position of the actuator relative to the surface and an actual position of the actuator relative to the surface for each actuator for three or more desired positions; wherein the determining the offset comprises selecting one of said two or more actuators and setting only the selected actuator to a non-operative by-pass mode, the other actuator(s) being active; the method comprising performing a first, normal rigging step, comprising: commanding the other actuator(s) to position the surface to a desired neutral position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the desired neutral position; adjusting the other actuator(s) until the surface is at the desired neutral position; store the amount of adjustment of the selected actuator as a first rigging parameter; the method further comprising performing a second synchronization step, comprising: commanding the other actuator(s) to position the surface at a second position above or below the neutral position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the second position; further adjusting the other actuator(s) until the surface is at the second position; storing the amount of adjustment of the selected actuator required to bring the surface to a second position as a second rigging parameter; commanding the other actuator(s) to position the surface at a third position below or above the neutral position, on an opposite side of the neutral position to the second position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the third position; further adjusting the other actuator(s) until the surface is at the third position; storing the amount of adjustment of the selected actuator required to bring the surface to the third position as a third rigging parameter; repeating the above steps for each other actuator; controlling the actuation system with a compensation factor based on the first, second and third rigging parameters. commanding the other actuator(s) to position the surface to a desired neutral position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the desired neutral position; commanding the other actuator(s) to position the surface at a second position above or below the neutral position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the second position; further adjusting the other actuator(s) until the surface is at the second position; storing the amount of adjustment of the selected actuator required to bring the surface to a second position as a second rigging parameter; commanding the other actuator(s) to position the surface at a third position below or above the neutral position, on an opposite side of the neutral position to the second position; measuring the actual position of the surface, said measurement including a measurement of the amount of adjustment at the piston rod of the selected actuator, and comparing the actual position to the third position; further adjusting the other actuator(s) until the surface is at the third position; storing the amount of adjustment of the selected actuator required to bring the surface to the third position as a third rigging parameter; repeating the above steps for each other actuator; controlling the actuation system with a compensation factor based on the first, second and third rigging parameters.
