Repetitivna regulacija hitrosti sinhronskega stroja s trajnimi magneti

SUŠIN, DENIS (author), Nemec, Mitja (mentor)

V pričujočem delu je predstavljena vektorska regulacija sinhronskega stroja s trajnimi magneti, pri čemer je poudarek na nadgradnji sistema z repetitivnim regulatorjem. Osnovna obravnava je podana za sinhronski stroj s tajnimi magneti, razsmernik, PID regulacijo in za osrednjo tematiko – repetitivno regulacijo. Dodatno so predstavljeni štirje načini izračuna vrtilne hitrosti iz kota zasuka in štirje načini izračuna kotnega pospeška. Na kratko je predstavljen tudi strojni del s pripadajočo močnostno in krmilno elektroniko. Nadalje je opisan razvoj režimov delovanja ter načini za odpravljanje posledic samodržnega navora z uporabo repetitivne regulacije. Izvedena je primerjava med režimi delovanja ter obrazložena smotrnost uporabe repetitivnega regulatorja v prostem teku. Dodana je še simulacija obremenitve s periodičnim značajem – umetna motnja. Na koncu so opisane omejitve ter možnost implementacije repetitivne regulacije v praksi.

Abstract

In this thesis vector control of permanent magnet synchronous machine is presented, with the main scope in an upgrade of classical control with repetitive controller. Basic explanations are given for permanent magnet synchronous machine, inverter, classic PID control and for the main topic – repetitive control. Additionally, calculation of speed from position in four different ways and calculation of acceleration (in also four different ways) is presented. The mechanical part is described briefly, likewise associated electronics. Modes of operation are described next. There are also described ways of minimizing consequences of cogging torque with usage of repetitive controller. Further comparison among modes of operation is done and the merit of repetitive control in free run is explained. Simulation of periodical load is added, too. In the end the limitations and practical implementation of repetitive controller are explained.
