Beschreibung
Zusammenfassung:	The invention belongs to the technical field of gas turbine control, and discloses a servo valve redundancy servo control method and system, and the method comprises the steps that a controller issues a first LVDT deviation value to a first servo card, and issues a second LVDT deviation value to a second servo card; the first servo card corrects a first LVDT feedback value according to the first LVDT deviation value, obtains a first LVDT feedback correction value and a valve position instruction, obtains a first servo valve driving signal of the current control period according to the first LVDT feedback correction value and the valve position instruction, and sends the first servo valve driving signal to the servo valve; and the second servo card corrects a second LVDT feedback value according to the second LVDT deviation value, obtains a second LVDT feedback correction value and a valve position instruction, obtains a second servo valve driving signal of the current control period according to the second LV
