Abstract	U ovom radu je opisan matematicki model asinkronog motora, detaljno je objasnjena transformacija velicina u dvoosni koordinatni sustav i prebacivanje u sustav relativnih jedinica. Iznesena je teza o promjenjivosti induktiviteta prilikom direktnog uklopa koja se temelji na slicnim pojavama kod sinkronih generatora. Model asinkronog motora prenesen je u prostor varijabli stanja. Napravljen je kratki pregled genetskog algoritma i MATLAB funkcije ga optimizacijskog programskog paketa. Takoder je predocen algoritam koji omogucuje identikaciju promjenjivih parametara. Obavljenja su mjerenja napona, struje i brzine vrtnje za vrijeme zaleta direktnim uklopom te je na tim podacima napravljena estimacija parametara stroja. Estimacija se bazira na rjesavanju matematickog problema minimizacije najmanjih kvadrata. Nakon vise provedenih estimacija s razlicitim parametrima algoritma predstavljeni su i komentirani rezultati.
Abstract (english)	A mathematical model of an induction motor, a transformation of variables to direct-quadrature reference frame and conversion to per-unit system is shown in this master thesis. The assumption of variable inductance during free acceleration test of an induction motor, based on similar phenomena occurring with synchronous generators, is presented. Mathematical model dierential equations are converted to state-space model. A short overview of the genetic algorithm is given, including MATLAB function ga of Global optimisation toolbox. An algorithm for applying GA for estimating variable parameters is explained. The measurement of current, voltage and speed are carried out during the free acceleration test and results are used to perform parameter estimation. The estimation is based on least squares minimization problem. Several estimation results are shown and commented on.
