Abstract

Diplomski rad bavi se utvrđivanjem najčešće korištenih modernih strategija upravljanja strujom i strategija širinsko-impulsne modulacije (ŠIM) za primjenu u električnim vozilima. U radu su dâne dinamičke jednadžbe i matematički modeli asinkronog motora te sinkronog motora s uzbudnim namotom. Priložene su upravljačke sheme za oba motora te je objašnjen njihov način rada. Za sinkroni motor s uzbudnim namotom objašnjene su i uspoređene dvije strategije upravljanja: maksimalni moment po struji i maksimalni moment po snazi. Objašnjene su tri strategije širinsko-impulsne modulacije: sinusna ŠIM, sinusna ŠIM s injektiranim trećim harmonikom i vektorska ŠIM. Sve tri ŠIM varijante su simulirane u MATLAB Simulink okruženju s istim električni pogonom. U nastavku su prikazane struje, naponi, momenti i ŠIM signali za sve tri varijante u stacionarnom stanju u ovisnosti o naponu međukruga, pretvaraču, sklopnoj frekvenciji i uvjetima simulacije.

Abstract (english)

The master thesis considers the identification of the most common state-of-the-art current control strategies and pulse-width modulation (PWM) schemes in automotive applications. The paper presents dynamic equations and mathematical models of induction motor and electrically excited synchronous motor. The control schemes for both motors are enclosed and explained. For an electrically excited synchronous motor, two control strategies are also explained and compared: maximum torque per ampere (MTPA) and maximum torque per watt (MTPW). Three pulse-width modulation strategies are explained: sinusoidal PWM, sinusoidal PWM with third harmonic injection, and vector PWM. All three PWM variants are simulated in a MATLAB Simulink environment with the very same powertrain model. The comparison in currents, voltages, moments, and PWM signals is given for all three variants in the steady-state in dependence on the DC link voltage, inverter, switching frequency, and simulation conditions.
