Simulation of a DC motor drive in Matlab

Tema i zadatak ovog završnog rada je bila simulacija elektromotornog pogona s istosmjernim motorm u Matlabu. Kako bi simulacija bila uspješno postignuta i razumljiva, najprije je bilo neophodno se upoznati s istosmjernim motorom. Tako se u prvom dijelu završnog rada opisuju dijelovi istosmjernog motora, njegov princip rada i različiti načini njegove uzbude. U drugom dijelu se opisuje elektromotorni pogon, njegova uloga i princip rada. Također se opisuje motorski i generatorski način rada te njegova statička stanja. Nakon teorijskog dijela slijedi praktični dio u kojemu su simulirana dva modela elektromotornog pogona s istosmjernim motorom, elektromotorni pogon s istosmjernim motorom temljen na tiristorskom ispravljaču kroz regulaciju momenta te elektromotorni pogon s istosmjernim motorom bez četkica kroz regulaciju brzine. Promatrali smo kut paljenja tiristroskog ispravljača, napon armature, struju armature, elektromagnetski moment te brzinu.The topic and task of this final work was a simulation of DC motor drive in Matlab. In order to successfully achieve and comprehend the simulation, it was necessary to first become familiar with the DC motor. The first part of the final work describes the components od the DC motor, its operational principle, and different versions of its excitation. The second part discusses the DC motor drive, its role and working principles. Additionally, it explains both the motor and generator modes of operation, along with its static states. Following the theoretical segment, the practical part follows, where two models of DC motor drives were simulated. The first model is based on a thyristor rectifier with torque regulation, while the second model involves a brushless DC motor with speed regulation. Parameters such as thyristor firing angle, armature voltage, armature current, electromagnetic torque, and speed were observed and analyzed
