1. An engine control system comprising:
a fuel controller that directs supply of fuel to a turbine engine based on a fuel control signal;
an electric machine controller that directs one or more electric machines to apply positive torque to the turbine engine based on an electric machine control signal;
a signal allocator electrically coupled to the fuel controller and the electric machine controller that generates the fuel control signal and the electric machine control signal from an error signal; and
a signal combiner electrically coupled to the signal allocator, wherein the signal combiner receives a feedback signal from the turbine engine and a rate command signal, and wherein the signal combiner generates the error signal by subtracting the feedback signal from the rate command signal.
