Abstract: A brake control system includes a servo valve and a brake control unit in electronic communication with the servo valve. The servo valve is configured to receive a hydraulic fluid and provide the hydraulic fluid to apply braking force to a wheel via a hydraulic line. The brake control unit is configured to calibrate the servo valve and determine whether a calibration of the servo valve was successful. In response to the calibration of the servo valve being successful, the brake control unit can operate the servo valve in an open-loop system. In response to the calibration of the servo valve being unsuccessful, the brake control unit can operate the servo valve in a closed-loop system.

Abstract: A brake control system of the present disclosure calibrates a servo valve and calculates a calibrated transfer function associated with the servo valve for precise braking in open-loop mode. The calibration steps may include determining i) whether an aircraft is on a ground surface, ii) whether the aircraft is not moving relative to the ground surface, and iii) whether braking is applied to a brake system of the aircraft. The brake control unit may calibrate the servo valve in response to the brake control unit determining that i) the aircraft is on the ground surface, ii) the aircraft is not moving relative to the ground surface, and iii) the braking is not applied to the brake system of the aircraft. The calibration process includes sending two or more test currents to the servo valve, and determining braking pressures associated with those test currents to calculate the transfer function.
