METHOD FOR CHECKING THE PLAUSIBILITY OF THE TORQUE OF AN ELECTRICAL MACHINE AND MACHINE CONTROLLER FOR CONTROLLING AN ELECTRICAL MACHINE AND FOR CARRYING OUT THE METHOD |
摘要 |
A method for checking the plausibility of a torque of an electric machine, calculated on the basis of a machine model, in which a first value of an electromagnetic power of the electric machine is determined from the calculated torque and a rotational speed of the electric machine. Stator current components and stator phase voltage components are calculated from the stator currents and the stator phase voltages with respect to a reference system, which is fixed in relation to the stator. A second value of the electromagnetic power of the electric machine is determined from the stator current components and the stator phase voltage components. If a deviation of the first value of the electromagnetic power of the electric machine from the second value exceeds a predefined power threshold value, the torque of the electric machine, calculated on the basis of the machine model, is classified as implausible. |
