Abstract
A vector control method for a synchronous machine, in particular a permanent magnet synchronous machine is provided. Q-axis and D-axis target currents are determined by respective allocations which link a target torque and a target flow rate to the Q-axis target current and the D-axis target current, respectively, without taking into consideration a voltage variation of a voltage to be applied to stator windings of the synchronous machine. The voltage variation is adjusted or compensated for beforehand by adapting the target flow rate. A control unit which is designed and programmed to carry out the vector control method is also provided.
Claims12
A vector control method for a synchronous machine having stator windings, the method comprising:
- determining Q-axis and D-axis target currents by respective associations which link a target torque and a target flux to the Q-axis target current and the D-axis target current, respectively, without taking into consideration a voltage variation of a voltage to be applied to the stator windings of the synchronous machine,
- adjusting or compensating for the voltage variation beforehand by adapting the target flux.
