FSR control frequently balancing

Good Evening,

we have a small power turbine which is running under fuel gas, After starting the turbine the FSR keeps changing from Speed load control to minimum fuel to acceleration phase and so on which causes a big variation in the speed of the turbine. also the fuel gas valve MOV is moving between 12 and 20%. i checked the logic and every thing seems OK.

we changed one speed sensor because it's giving from time to time spikes but still we have the same problem.

we have GE Fanuc controllers on site.

can you help me please!!
 
What kind of turbine is this? If I had to guess I'd say a small gas compress by nouvo pignone?
