摘要： A method for determining electric currents for an electrical machine includes generating a first real power current demand signal and a first reactive power current demand signal. The method also includes determining at least one of a second real power current demand signal and a second reactive power current demand signal by prioritizing a second real power current demand signal over a second reactive power current demand signal. Alternatively, the method also includes determining at least one of a second real power current demand signal and a second reactive power current demand signal by prioritizing the second reactive power current demand signal over the second real power current demand signal. The method further includes comparing at least one of the first real power current demand signal and first reactive power current demand signal to at least one electrical machine current limit signal.
