摘要: The present disclosure relates to a control system for an electric working vehicle comprising a first component associated with a first rotor and a second component associated with a second rotor. In use, the first rotor is associated with a first noise waveform and the second rotor is associated with a second noise waveform. Furthermore, in use, the vehicle is associated with a resultant noise waveform comprising the first and second noise waveforms. The control system is configured to control an angular position of the first and/or second rotor such that a parameter associated with the resultant noise waveform is optimised. In this manner, the noise performance of the vehicle can be improved.

摘要: A system comprises a load machine (175), a coupler (160) and an electric machine (150). The electric machine (150) is coupled to the load machine (175) via the coupler (160) and configured to drive the load machine (175). A controller (110) is configured to control the electric machine (150) based on a drive impedance of the electric machine (150) and an impedance of the load machine (175) and the coupler (160).
