Abstract: A method for controlling a hybrid machine is disclosed. The hybrid machine may be equipped with a turbine engine, a generator connected in series with the turbine engine, an electrical energy storage device, and a motor drivingly connected to a power output component for the hybrid machine. A controller may receive a power demand signal, determine a power level in the electrical energy storage device, determine available inertial energy stored at least in rotating components of the turbine engine and the generator, and provide one or more control signals to selectively control powering the turbine engine to full power, selectively turn off all fuel to the turbine engine, selectively store excess energy as electrical energy by directing excess electrical energy from the generator to the electrical energy storage device, and selectively store excess energy as inertial energy.

Abstract: A method of indicating a fault associated with a non-combustion chamber of an engine includes monitoring a fluid intake pressure for the engine, monitoring a pressure for a non-combustion chamber of the engine, and indicating a fault associated with the non-combustion chamber based on a difference between a first non-combustion chamber pressure and a second non-combustion chamber pressure being below a chamber threshold value.
