摘要 |
The invention relates to a method for operating an induction machine (1) containing a pulse-controlled converter (2), comprising the following steps: determining one current target value (lq, Target, Id, Target) for each current in a longitudinal and/or transverse directions on the basis of a predetermined torque (MRef), detecting one voltage target value (Uq, Reg, Ud, Reg) for each voltage in the longitudinal and/or transverse directions on the basis of the current target value (lq, Target, Id, Target) and/or a current actual value (lq, Actual, Id, Actual) determined at the pulse-controlled converter, controlling and/or regulating the induction machine (1) in accordance with the determined voltage target value (Uq, Reg, Ud, Reg). It is intended that, using a model, a model value (Uq, Model, Ud, Model) is determined for each voltage in the longitudinal and/or transverse directions, the difference between the voltage target value (Uq, Reg, Ud, Reg) and the model value (Uq, Model, Ud, Model) is calculated and when a predetermined maximum difference is exceeded, an error signal is triggered. |
