Abstract

U radu je prikazan izvod modela asinkronog stroja u prostoru stanja. Na osnovu modela u prostoru stanja izrađen je model stroja u programskom paketu Simulnik. Provedena je simulacija zaleta asinkronog stroja kojom se potvrdila ispravnost razvijenog modela. Dan je pregled različitih metoda kojima se vrši identifikacija parametara asinkronog stroja. Opisane su razlike između offline i online metoda estimacije, te su nabrojane i ukratko opisane neke metode iz navedenih grupa. Odabrana je jedna... More metoda identifikacije koja je testirana na prethodno razvijenom modelu u Simulink-u. Pokazalo se da odabrana metoda ne određuje sve parametre motora jednako kvalitetno, te da bi je, za implementaciju u stvarnom pogonu, trebalo dopuniti dodatnim postupcima koji bi omogućili kvalitetniju identifikaciju.

Abstract (english)

This thesis provides an overview of developing a state space model of an induction machine. A Simulink model of an induction machine is built, based on a developed state space model. Simulation of a direct start up was made to show that the Simulink model was functioning correctly. An overview of different methods for parameter identification was given, with descriptions of offline and online estimation methods, some examples of offline an online estimation methods were shortly described.... More One identification method was chosen, and tested on a previously developed Simulink model. Results show that selected method is not suitable for estimation of all induction machine parameters, as it estimates some parameters, said being resistances, with precision, while it deviates with estimation of other parameters, said being inductances. Inability of tested method to successfully identify all parameters implies that it should be applied as a part of a more complex identification method that can successfully estimate inductances of a induction machine.
