There is provided a system including a dual rotor electrical machine. The dual rotor electrical machine comprises a stator, an inner rotor including a first number of permanent magnet pole pairs, and a modulator including a second number of modulating segments. The system includes a controller configured to execute non-transitory machine readable instructions that, when executed by the controller, cause the system to determine a virtual position of an electromagnetic field of the stator based on a weighted sum of an angular position of the inner rotor and an angular position of the modulator, wherein weights in the weighted sum are based on the first number and the second number.
