Abstract

According to an aspect, a system includes a starter air valve (116) in fluid communication with an air turbine starter (120) to drive motoring of a gas turbine engine responsive to a compressed air flow (108) from a compressed air source (114). The system also includes a variable-position electromechanical device (104) operable to adjust positioning of the starter air valve (116) and a discrete-position electromechanical device (106) operable to adjust positioning of the starter air valve (116) and limit a motoring speed of the gas turbine engine below a resonance speed of the gas turbine engine responsive to a pulse width modulation control based on a failure of the variable-position electromechanical device (104).
