HEALTH MONITORING SYSTEMS AND METHODS FOR SERVO VALVES

A system (200) for performing frequency response health monitoring of a servo valve (252) prior to flight of an aircraft (100) may comprise: the servo valve (252); and a brake controller (208) in electrical communication with the servo valve, the brake controller configured to: determine the brake controller is powering up, supply a variable current to the servo valve to perform the frequency response health monitoring to the servo valve in response to determining the brake controller is powering up, and determine a health status of the servo valve based on the frequency response health monitoring.
