Assignee: GENERAL ELECTRIC COMPANY
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  B | IPC B  F

Claim 0:
1. A gas turbine engine, comprising:
a power turbine mechanically coupled with a load; and
one or more processors configured to:
determine a first fuel flow demand based at least in part on a power demand rate associated with the load;
determine a second fuel flow demand based at least in part on a power turbine speed error associated with the power turbine and a power turbine speed error rate derived from the power turbine speed error;
determine a third fuel flow demand based at least in part on the power turbine speed error;
determine a composite fuel flow demand based at least in part on the first fuel flow demand, the second fuel flow demand, and the third fuel flow demand; and
control a fuel flow to the gas turbine engine based at least in part on the composite fuel flow demand.
