PROBLEM TO BE SOLVED: To provide a fuel valve opening degree control system for preventing failure of operation of a valve element of a fuel adjusting valve without having influence on output load, and performing good fuel control. SOLUTION: An opening degree variation function generator 14 gives an opening degree variation instruction value to any of two or more fuel adjusting valves 12 when an combustor 11 runs at constant load, while a opening degree variation correcting function generator 16 gives an opening degree variation compensating instruction value for offsetting fuel flow rate variation against the opening degree variation instruction value to the rest of the fuel adjusting valves 12. Thereby, opening degree of the fuel adjusting valve 12 can be varied while holding load-constant running, so that failure of operation of the valve element can be prevented. COPYRIGHT: (C)2004,JPO
