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.
