Abstract
Embodiments include a method for operating a hybrid machine system including an electric machine coupled to an engine and an inverter in an offset determination mode, and in an operating mode when the electric machine is in a loaded electrical state. Operating the machine system in the offset determination mode may include (1) receiving mechanical angular position information representative of mechanical angular positions of the electric machine, (2) receiving electrical angular position information representative of electrical angular positions of electric signals in the electric machine when the electric machine is operating in an unloaded electrical state, (3) determining an offset between the mechanical angular positions and the electrical angular positions, and (4) storing the offset. Operating the machine system in an operating mode may include (1) receiving the mechanical angular position information, (2) generating machine control signals based on the mechanical angular position information and the stored offset, and (3) applying the machine control signals to the inverter.
