Visokodinamičen električni pogon sirene

TURK, MATEJ (author), Fišer, Rastko (mentor)

Povzetek Cilj diplomske naloge je realizirati natančno vodenje sinhronskega motorja s trajnimi magneti. Na rotor motorja je pritrjena sirena, ki pri obratovanju oddaja zvok točno določene frekvence. Vodenje motorja se izvaja z uporabo frekvenčnega pretvornika in krmilnika gibanja, trenutni položaj rotorja pa se meri z inkrementalnim dajalnikom. V delu bom predstavil postopke, kako pravilno nastaviti frekvenčni pretvornik in krmilnik gibanja. Opisal bom tudi program za krmilnik gibanja, ki zagotavlja ustrezno vodenje motorja. Za lažje razumevanje načina vodenja je v začetku diplomskega dela predstavljeno delovanje sinhronskega motorja s trajnimi magneti, področje uporabe ter njegove prednosti in slabosti. Predstavljen je tudi princip delovanja frekvenčnega pretvornika in inkrementalnega dajalnika. Sledi opis strojne opreme, ki je potrebna pri vodenju pogona. Poudarek je predvsem na frekvenčnem pretvorniku Danfoss FC 302 in krmilniku gibanja MCO 305, katerega značilnost je visoka natančnost ter dinamika vodenja. Ob vsaki komponenti sem podal nekaj ključnih tehničnih podatkov. V nadaljevanju je predstavljeno delo s frekvenčnim pretvornikom, na katerem je potrebno ustrezno nastaviti vrsto parametrov, da vzpostavimo delovanje pogona. Opisano je tudi programsko okolje Aposs, v katerem razvijamo kodo za ustrezno vodenje servo pogona. Zadnje poglavje vsebuje navodila za uporabo aplikacije pogona sirene oziroma nekakšen uporabniški priročnik, da bo lahko vsak uporabnik brez posebnega predznanja z aplikacijo upravljal ali vnesel novo programsko kodo za poljubno skladbo.

Abstract

Abstract The aim of the thesis is to realize precise control of permanent magnet synchronous motor. On a motor's shaft a siren is mounted, which during rotation emits sound of exactly defined frequencies. Frequency converter with motion controller is used for motor control and rotor position is measured by incremental encoder. In the first part of the thesis procedures how to properly set frequency converter and motion controller are introduced. Then follows a description of a program which is responsible for the proper communication between the motor and motion controller. For better understanding of permanent magnet synchronous motor’s operation, his role in modern electric drives and advantages and disadvantages are presented. Frequency converter and incremental encoder principle of operation is also explained. Then follows a description of hardware components of the drive. Focus is mainly on frequency converter Danfoss FC 302 and motion controller MCO 305, which is characterized by high accuracy and dynamic capability. For every component some key technical data are given. Practical work with frequency converter, in which it is necessary to properly set number of parameters to establish correct operation of the drive, is presented. Software environment Aposs, which is responsible for the proper drive control is also described. The last chapter introduces instructions how to use presented drive to generate the desired melody. Each user without a special knowledge can enter new program code for any optional song.
