Popis: Many applications of induction machines require a model and its electrical and mechanical parameters. The parameters can be estimated during the machine's operation in closed-loop by recursive algorithms. On-line estimation algorithms can yield suitable results when parameter identifiability is guaranteed. This work analyzes the identifiability of the induction machine by the condition of sufficient excitation. The result is a reduced model order and a condition on the machine operation to yield useful parameter estimates. The practicality of the presented method is shown on data from a real test bed. Additional emphasis is put on signal processing to compute the necessary first and second derivative of noisy measurements.
