| Abstract |
For the purpose of flux oriented control a standard observer structure is applied to get the unmeasurable rotor flux of an induction motor. Main emphasis is put on discrete-time considerations with respect to microprocessor realizations. This aspect concerns the internal observer structure as well as the data acquisition and sampling strategy, which is synchronized with the pulse width modulation. Measurement results show that the proposed observer provides good results for both motor and generator operation modes and even at standstill. Moreover, the inherent parameter robustness of the used structure is
demonstrated. |
