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

Claim 10:
11. A vehicle, comprising:
a rotor;
a gas turbine engine mechanically coupled with the rotor, the gas turbine engine including a power turbine; and
one or more processors configured to:
determine, by executing a feedforward module, a first fuel flow demand based at least in part on a power demand rate associated with the rotor of the vehicle;
determine, by executing an aggressive control module, a second fuel flow demand based at least in part on a power turbine speed error associated with the power turbine, a power turbine speed error rate derived from the power turbine speed error, and a bandwidth of the one or more processors executing the aggressive control module;
determine, by executing a power turbine governor module, 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.
