Abstract
U ovom diplomskom radu detaljno je opisan dinamicki matematicki model istosmjernog ne- zavisno uzbudenog motora te asinkronog motora, te dvoosna teorija elektricnih strojeva. Po- sebna paznja pridodana je opisivanju mehanickog vladanja istosmjernog i asinkronog stroja, te je izraden simulacijski model osovinskog spoja istosmjernog generatora i asinkronog motora u programskom paketu Matlab/Simulink. Deniran je problem estimacije parametera opcenito te njegova primjena na slucaju estimacije momenta tromosti i radnog otpora istosmjernog genera- tora. Estimacija se u ovom diplomskom radu temelji na minimiziranju funkcije cilja s kriterijem najmanje kvadratne udaljenosti. Ukratko je opisan izabrani alat za estimaciju parametara, te njegova primjena u programskom paketu Matlab. Napravljena su mjerenja faznih napona i linijskih struja mreze, napona armature i struje armature istosmjernog generatora te elektricne brzine. Na kraju su prikazani rezultati estimacije parametara te je provedena statisticka analiza dobivenih rezultata i reziduala. Na temelju dobivenih rezultata i provedene statisticke analize dan je zakljucak.
Abstract (english)
In this master thesis, a dynamic mathematical model of separately excited DC machine and induction machine as well as the reference frame theory is thoroughly explained. Special atten- tion was given to explaining the mechanical behaviour of DC and induction motor. Simulation model of axle coupling between a DC motor and induction motor was developed in Matlab/Si- mulink software. The parameter estimation problem is dened in general, and its application in the case of estimating the moment of inertia and resistance of DC generator. Parameter estimation, in this master thesis, is based on minimizing the objective function with least squ- ares criterion. Selected parameter estimation tool and its application in Matlab software is described brie y. Measurements of phase voltages and line currents of the grid, armature vol- tage and current of DC generator as well as of electric speed were made. Finally, the results of parameter estimation were presented, and a statistical analysis of the obtained results and residuals was performed. Based on the obtained results and carried out statistical analysis, a conclusion is given.
