A system is provided for speed control during motoring of a gas turbine engine (10A, 10B) of an aircraft. The system includes an air turbine starter (120A, 120B), a starter air valve (116A, 116B) operable to deliver compressed air to the air turbine starter (120A, 120B), and a controller (102A, 102B). The controller (102A, 102B) is operable to adjust the starter air valve (116A, 116B) to control motoring of the gas turbine engine (10A, 10B) based on measured feedback with lead compensation to reject disturbances attributable to dual to single or single to dual engine starting transitions.
