ABSTRACT:
An aircraft brake actuation system implements an anti-hysteresis feature that compensates for various hysteresis effects exhibited in an aircraft brake actuation system due to one or more sources of mechanical inefficiency within the system. The anti-hysteresis feature adjusts the command signal up or down, depending on the direction of the command, a predetermined amount based on the amount of hysteresis in the system. By doing so, the actual brake force supplied to the aircraft brake elements more accurately represents the brake force being commanded.
