Abstract

Korišteni mikrokontroler za izvedbu algoritma upravljanja je Piccolo F28027 proizvođača Texas Instruments. Ostvarene modulacije, u bipolarnoj i unipolarnoj inačici, prema izboru signala reference su sinusna modulacija (frekvencijski pretvarač) te istosmjerni pretvarač (DC Chopper). Izbor signala nosioca također je omogućen programom te može biti: trokutni signal, rastući pilasti signal ili padajući pilasti signal. Ostvarena je i podrška za upravljanje do 4 nezavisna motora ovisno o zahtijevanom broju faza (max. 4 faze). Parametri signala reference i signala nosioca u potpunosti su podesivi unutar određenog raspona vrijednosti. Dobivene modulacije snimljene su osciloskopom i testirane korištenjem IGBT mosta L298n proizvođača STMicroelectronics. Uz rad je priložen i kod napisan u programskom jeziku C

Abstract (english)

Microcontroller used for implementation of control algorithm is Piccolo F28027 made by Texas Instruments. Accomplished modulations, in bipolar and unipolar versions, according to reference signal are sine modulation (frequency converter) and DC converter (DC Chopper). Choice of carrier signal has also been made possible between: triangle signal, up sawtooth signal and down sawtooth signal. Support has been made for independent contolling of up to 4 motors depending on phase count (max. 4 phases). All parameters of carrier and reference signals are completely adjustable within specified range of values. Gotten modulations have been recorded by oscillosope and tested using IGBT bridge L298n made by STMicroelectronics. Code written in C programming language is supplied.
